Welcome. You asked about happiness now. Well......I was "in" for over thirty years. My husband and I were baptised in Dec. of 1973, scared to make it just in time for the big A which was to come in 1975! My parents hated the Witnesses, and we had a strained relationship.
Finally, my daughter was df'd at 16 for some silly teen stuff(such as take a few puffs off a cigarette, etc., but falsely accused of fornication) , treated HORRIBLY...
My husband and I were devastated and tried to stay in. We wrote the Society just knowing that our injustice would be straightened out. Ha! We got the most wishy washy letter back....were told by an elder, "Even though mistakes were made, you must accept what happened, because God has allowed it."
At any rate, fast forward...we left-had had enough-but now we had no friends, my dad was dead, and my mother was ill and had dementia. After lots of depression, I decided to go back to school...now at sixty, I will graduate next December. Happy? Well, happier. It is as if I was in some sort of time warp for the thirty plus years. If only I could go back and do it over without the WTS.
You are young, and you have an education. You have a bright future ahead. Things may get rough with your family. Please hold on to at least a little sense of humor-it will help in the long run. Try lots of different activities to find out who the true you is. Now you have some time to get hobbies the WTS said you shouldn't have because the end was sooooooo close.
