Before deciding if you should be a Jehovah's Witness or not, here's what you need to know about joining about any socially isolated religious group that encourages members to associate only with fellow believers.
Some people who are unhappy with their current religion or life in general, find that socially isolated religious groups like the Jehovah's Witnesses are extremely attractive. Here's why.
People who are lonely, depressed, or unhappy in some way with their life are attracted to close knit religious communities that teach wholesome values such as respect and love for one another. 
When someone shows a genuine interest in joining the Jehovah's Witnesses, they are showered with love and affection like they've never experienced before. The instant attention and wholesome friendships convinces new people that they have found 'the truth' even when they are uncertain of some doctrines. 
Why do Jehovah's Witnesses give so much love and attention to people who are interested in joining? Because they take their preaching work seriously. Since they believe that only Jehovah's Witnesses will survive 'armageddon', it's important for them to covert non believers to their religion as soon as possible. To do this, they practice 'love bombing'. i.e. they shower newly interested people with an unusual amount of love. 
Instant love and hundreds of new friends is the bait. Young people who have been raised as Jehovah's Witnesses are also shown extra attention, encouragement, and peer pressure to 'dedicate their life to Jehovah'.
The problem is that this special love and attention is designed to control and manipulate unbaptized Jehovah's Witnesses into becoming a baptized Jehovah's Witness.
Jehovah's Witnesses practice 'conditional' love. It is dependent upon you being 'teachable', humble, obedient, agreeable, like-minded, etc. ...  
The day after you get baptized everything changes. The 'love bombing' stops. The entire purpose of showing you so much love was to convince you to join. Now that you're a member, there's no need to show you special attention like they did before.
Now as a baptized Jehovah's Witness, you are accountable and your life suddenly changes. You now 'belong' to the organization (almost as if you are their property). You are expected to obey everything you're told.  If you break any of their rules and do not repent, you are disciplined and shunned forever. 
The practice of shunning is uncomfortable and emotionally upsetting for both Jehovah's Witnesses and those who leave. When you're out in public, your JW parents, grandparents, children, brothers, sisters, aunts, uncles, cousins, friends, etc. ... will walk right by you without looking at you or even saying a greeting. Every day you're reminded that your own family doesn't love or respect you enough to say, 'Hi, How are you?'. Their love is conditional upon you returning to the Watchtower organization. They have chosen to put their religion ahead of their relationship with you. 
Shunning is forever. You will be treated as if you are literally dead (subject to rare exceptions). If you're a baptized JW and want to leave the organization for any reason, your JW relatives are required to shun you forever or be shunned themselves. JW's inside and outside the organization grieve the loss of loved ones. Some haven't seen or heard from their relatives in decades. The practice of disfellowshipping and shunning began in 1952 
It's important to underline that even though you have no intentions of ever leaving Jehovah's organization, you can't control what your parents, children, or other family members might do. They might leave and you might stay. Either way, the organization says it's 'God's command' that you shun everyone who leaves the organization. 
Millions have left and are leaving. Even though JW's don't believe in good luck or bad luck, the mathematical odds are good that some or all of your family will leave. It might be this year, next year, ten years from now or thirty years from now. If someone dear to you leaves anytime in the future you must shun them. Are you prepared to do that?
In the real world, genuine friendships develop over time. If you're floored by how much the Jehovah's Witnesses love you as a stranger, remember that the love is fake. They have an agenda. They want you to join their religion. 
If you get baptized their job is done. The love bombing stops. They've proved to Jehovah they are somewhat more worthy of eternal life because they brought you into the safety of the Watchtower religion before armageddon.  They also get love and recognition from fellow Jehovah's Witnesses for bringing you 'into the truth'.
If you want good friends and community there are better places to find what you're looking for. Just remember that normal people will not instantly 'love bomb' you (and then instantly drop you as a friend later). Normal, healthy relationships develop slowly over a long period of time.
If you're lonely and looking for new friends who share your interests, here are some ideas on where you can find good people.
Jehovah's Witnesses must be separate from the world like all other socially isolated religious groups. Here's what critics say about isolation from the world and Jesus taught exactly the opposite of what the organization teaches.
Although Jehovah's Witnesses are friendly with non believers at work and in public places, they associate with fellow believers. See Friendship With A Jehovah's Witness
'Bad' associations includes everyone who does not belong to the Watchtower religion. Jehovah's Witnesses must associate only with believers. the organization says, 'What does this account teach us? That we simply cannot socialize with unbelievers and hope to suffer no ill consequences. The Scriptures state that “bad associations spoil useful habits.” (1 Cor. 15:33) On the other hand, association with people who share your beliefs, your high moral standards, and your love for Jehovah is a safeguard. Such good association will encourage you to act wisely.—Prov. 13:20.' Watchtower magazine, June 15, 2010, Article: 'Finding Security Among God's People', par 15

Watchtower quotes: 'Obey Us'
Persecution of Jehovah's Witnesses who leave their religion. (Watchtower Quotes)
Watchtower Shunning Policy (with quotes from their literature)
Christians are baptized in the name of the Father, Son, and Holy Spirit. Matthew 28:18,19; They are under contract with God. Because of this, loyalty to their religion is not required. They are free to attend any Christian church without punishment. Jehovah's Witnesses are baptized in the name of Jehovah and baptism identifies them as one of Jehovah's Witnesses. This means they must obey all the rules of Jehovah's Witnesses. JW's are under contract with their religion and obligated to obey the organization instead of God alone. See the Baptismal Vows of Jehovah's Witnesses
Jehovah's Witnesses are not allowed to disagree. If you have doubts and someone questions you about what you believe, you must lie or risk being disfellowshipped and shunned. Jehovah's Witnesses are taught that 'theocratic lying' to protect the organization from harm is approved by the Bible and required by God.
Jehovah's Witnesses shun family members and friends who leave the organization because they are told they are being loyal to Jesus. However Jesus taught exactly the opposite of what the organization teaches today. Examine the evidence in this article Matthew 10:34. 'I did not come to bring peace, but a sword.'
Millions of former Jehovah's Witnesses (apostates) haven't heard from their JW relatives in decades. Disfellowshipping and shunning began in 1952
Jehovah's Witnesses don't believe they are saved by God's grace. They are saved by working hard for the Watchtower organization, obeying Elders, obeying Jehovah, and keeping all the rules of the organization. Since no one is perfect, JW's are never certain of salvation. Eternal life is the illusive carrot. They can see it ever so close but it's always out of reach. Jehovah's Witnesses never know if they've done Enough for Jehovah
If you look at Memorial Celebration of Jehovah's Witnesses you will see that millions of Jehovah's Witnesses do not have a relationship with Jesus, the path to eternal life. Only 'the faithful and discreet slave' (the Governing Body of Jehovah's Witnesses) is in relationship with Jesus. Everyone else must obey the Watcthower in hopes that some day Jehovah will grant them eternal life.
