BW,
Sorry about your parents. That's got to be a hard pill to swallow. Thank God you didn't get baptized. Lisa gives very good advice.
At this point, you don't have to be a good Jw. You can refuse meetings and service etc. Sounds like they are telling you to live a double life for their own status in the cong. If you refuse and they get abusive, call the cops first. (When the cops come for domestic problems, the reflection is so bad on your parents to the BORG, that they will likely be put on restrictions in the hall, and loss of elder status.) But that would be an extreme move on your part.
Unless your aunt get guardianship, your parents will have some control.
The good news is, at least you know where you stand.
Keep posting,
HBH
ps FORCING you to be a good JW, can be considered emotional abuse, get more info on that.
