Welcome to the forum. The first few weeks after getting out of the hospital are often the most difficult. You are out of the sheltered environment, and all the pressures that were on you before you went it are back now. My advice: reach out to your therapist, find a support group, keep posting and expressing your feelings here, and try not to isolate. The more things you can do to 'reconnect' the faster your transition from hospital life back to the 'real world' will be. You CAN do this. Remember (and I have to remind myself of this a lot too) that things do get easier. There will be setbacks... ups and downs... but LIFE IS WORTH IT!
As to idea of finding a support group... I was lucky enough to find one (peer led) that meets on a weekly basis. It's given me a place to share my innermost thoughts and fears without being judged (much like you can on this board), only even better because many of these people are now my friends, who I can do things with outside of the group
If I've learned anything in my recovery process, is that it is my own responsibility, and no one else can do it for me. I had to grasp the bull by the horns and MAKE MYSELF go to the support group, even when I was afraid, depressed and ashamed. I don't know your specific circumstances for being on this board, but I do believe that ALL PTSD sufferers deserve a chance at healing... a chance to reclaim your life. BEST WISHES DENICE.
