I grew up as a Jehovah's Witness. I felt so alienated going to school because I wasn't allowed to befriend any "worldly people" aka non witnesses. I couldn't (and still can't) celebrate holidays. Up until 4rd grade I pushed away a lot of people who were nice to me, just because of my upbringing.
I got really sick in 5th grade and was hospitalized for a month because my stomach stopped working and I had a painful cyst. No one from my kingdom hall came to visit besides 2 of the "elders". And the only people that came had no empathy at all, I was told when paradise comes I'll be healed blah blah.
That's when I started looking at this religion differently. I felt no warmth from them at all. So finally i decided to open up, and meet people outside of my religion. (Ironicallly they most supportive people.) I thought, "if the only people I was allowed to be befriend, were hypocrites, nitpickers and judgmental people (some of my family included; sleeping around, gossiping, etc) I dont want to be apart of this." And that was it for me. .
So now, I think I'm just agnostic. My family doesn't completely know yet. (mom and brother does). But even now some of my family looks down on me for not being bathtized yet (I'm 17). I have no idea if I want to be part of a religion anymore. Guess I'll find out in the future. Sorry for the long post.
