I am so sorry for what you have been through. From reading about everything you have tried so far I can see what a brave and strong person you are. Its notable how determined you are to get better. You already said that you have tried therapy and joined groups but I was wondering if you can try find someone or a group of people; perhaps with experiences similar to yours whom you can talk to. Being around people is in any case better than trying to fight on your own. Have you tried naturopathy therapies, health resort centers, self-help groups..? Maybe none of those things work but you never know until you have tried them and you might end up meeting some new friends or getting inspiration/motivation in a way. Maybe you have just not met the right kind of therapist/group yet. I think as long as you have the strength to get out of the house it would be good to keep trying out everything that is out there, in the hope to find something that works specifically for you. I hope you will feel better soon.
