I'm so sorry for all that's happened to you.
I will say that, although it seems like you had a support group when you were a JW, it was under false pretenses. I hope you can see that. Their love and affection is conditional. You may be loved bombed when you first walk back into a Kingdom Hall, but how long does it last before it dies out completely?
Bad things happen to good people, no matter their religion, belief system, or lack of belief. It's just a part of life. A support system can be formed from anywhere. This site itself is full of good people who have been to hell and back with this cult and are there for others as much as they possibly can. I see you've gotten a bunch of PM's, and no doubt these people have tried to be very encouraging to you. You will not find that kind of unconditional love and support from the JW's.
As was mentioned, look at this as an opportunity to start over. No matter your age, it's never too late. You had a long relationship that just ended...so take that time to re-evaluate you and your life and what you might want from a prospective partner. Have a relationship with YOU first. Moving on can be a very positive thing if you look at it in the right light.
I'm sorry you lost your mom. As was mentioned, that had nothing to do with you being in or out of the JW's. Illness and death happen, we lose people we love. It sucks, but it's the way life is. Being shackled to a cult doesn't change that.
Accidents happen. I'm glad you're okay, but please don't feel like this was some sort of divine retribution for you leaving the JW's. And if it were, why would you want to serve such a jerk of a god anyway? One who gives free will and then when you exercise it, he punishes you for it because your free will led you to make a choice different than what he wanted you to... It makes no sense.
You always have support here...from all of us. Even being far away, a kind word and a listening ear can help so very much.
