How do I make it in life when Im in pain a lot of the time?

26 M, been in pain for about 10 years now. Not 24/7 constant but fairly close to it. Im exhausted physically and mentally because of it and it’s really killed any drive I might have to do anything with my life . Yes I’ve been to doctors, therapists, physical therapists, with not much luck. It’s not a very well known issue that can just be fixed . Some days I really want to give up and call it quits but bills need to be paid still. Don’t expect a lot of people being able to relate to this but it would be nice to get some pointers or guidance on things I could do so my life doesn’t go to complete shambles
