This might sound difficult, but again just my experience. Have you tried any volunteer work? When I was so low and saw no way out it gave me a reason to keep living. They never minded me crying, or needing to run off to have a panic attack, they were just thankful that I gave up my time at all to help out. They appreciated how much hard work it was for me to get there. I have been there nearly 10 years now, its turned into my career, my dream job. I guess I got lucky finding such a great place on my first try but it could take a fair few goes to find something you have a passion for. I figure anything is worth a try when you felt you have tried everything.
