Welcome. Congratulations on your "waking up" at 21. Some of us didn't wake up until way way later.... So you still have your 20's ahead of you.
I would start creating a relationship with any non jw relative... the stronger the better... the more the better.. also with people outside a cult...
Become financially independent and if you can start learning more skills... ideally in school but nowadays you can learn a lot online...
Its like you are preparing for Armaggeddon... But this will be your personal one.. and the good news is that you might lose your family... but you wont lose your life... not yet :-) Sorry but there's no paradise with pet lions... your paradise started when you woke up... and it wont last forever.. so you better start enjoying whats left of it.
Keep reading... act very slowly right now.
