I'm with Shamus on this one....
The only good thing I remember is filling the chair piping full of gum during the prayer (I always picked the same seats to complete my mission).
Other than that, I can't remember anything. I was an outcast at the KH. People preferred to avoid me. At JW get-togethers, I'd sit there all by myself. Everyone would be talking to everyone else except me. I'd just sit there and watch everyone smiling and laughing while I sat in my own little world of depression. I quit going to JW gatherings after a while. This also had an effect on me after I left. I had trouble fighting depression when I was with a large group of people, even if they were all my friends who WOULD talk to me.
I have memories of going to the KH half an hour early for the association. I'd stand at the back of the hall, watching all the artificial smiles and fake happiness. Again, nobody would talk to me, and the sight of the whole thing depressed me.
So much time was wasted being unhappy. I had no choice since I was a teenager who had to obey my parents and go to the Kingdom Hall.
Coffee breaks were the highlight of service, since I got to eat something. Even those weren't all that exciting. Again, nobody would talk to me. If there was someone else my age there, I'd try to talk about something normal, and then I would get in trouble from my mother since I wasn't keeping the conversation spiritual. Better to say nothing at all than keep the conversation spiritual. WTF was I going to talk about? Jehovah created my shitty dress shoes that hurt my feet? Jesus would have loved to eat a dutchie?
I think the reason why I don't remember much about my JW years is because I blocked them out. It was too depressing to think about them. There was no happiness.
