How long have you been out tresdecu? It is challenging to lose your entire belief system and having to start over. I think one of the biggest challenges is to accept that we don't have all the answers, and that's ok. I've been out for 5 years, and things are definitely better than they were, although it was a very difficult journey to get to where I am today. I did have a time where I needed to take medication, and talking to a therapist helped as well.
It's nice to feel free, and not have a feeling of dread come over you Friday night when you realize you're expected to go on "service." Life is a process, happiness is something that comes and goes. Trying to find something that give you meaning in your life can help one feel better. It's a process finding that as well. And there is no hurry, it will come in time.
My brother in law suffers from debilitating depression, and because he's in "the truth," he won't go to a therapist because he fears they will "talk him out of being a JW." I find this incredibly sad. He is a very intelligent man who is wasting away because of this harmful religion.
To anyone who is struggling with depression, it can get better! I have been down so low that I didn't feel like life was worth living. Just take one day at a time, and I promise it will get better. <3
