Do all Jehovah Witnesses act like this?

I'm a minor (17) living with my parents, I'm an Atheist however I practice other Spiritual things, such as Astral Projection, Lucid Dreaming, and OBE's, I have many friends who practice in the same cat.

My mom found out about me being an Atheist after I mentioned it, she cut the computer that I helped paid (She only paid 10% while I paid 90%), she took my phone off of me and deleted all my contacts from there, who she didn't know, and who she thought was a bad influence. Now this phone is an iPhone so it's expensive and not to mention I paid my contracts for it and she didn't pay a damn penny. Then she found out about my boyfriend from one of her close friends when they were gossiping, now she's hacked into my account on FB and deleted it, as well as my Twitter. Despite this I kept my cool and never lost it, do all other Christians do this? What should I do? She told me I need to grow up, is that the case?

As you have just discovered, Jehovah's Witnesses are just as crazy as people who believe in Astral Projection and all your other fantasies. What does your father think about his wife's irrationality?

I don't know if you classify JW's as 'christians'. They believe that Jesus was a 'god' but not god. That's not the mainstream christian belief.

Yes, you need to grow up.
Your mother may not be doing things ideally, but she is trying to save you from dangers you take far too lightly.
Don't point a finger to your mother, look at yourself.

You are doing things that later in your life you will regret… I know by experience… Been there done that.

What she is trying to do is helping… Even you don't understand it.

Been there done that… And never again

You indeed need to grow up… I have a Christian mother that people would say are the worst of the worst when it comes to being strict. I would think she was making my life horrible and hated her for that but she was only protecting me and I thank her greatly for that now that i'm older. Just listen to your mother like the saying says.a mother knows best!

You are a spoiled and misguided child. Gain enough wisdom to listen to a mother who is trying her best to help you. When you reach maturity you will appreciate her help.
