Chronicity is one of the toughest problems to manage. I understand and sympathize. Do give yourself credit (lots of credit) for doing as well as you have to move on in life despite your feelings. That has taken strength and speaks to an inner core of health.
It doesn’t matter if others “have it worse”. Maybe they do. Maybe they don’t. Don’t waste your time talking with people who make that useless comparison. Every individual’s pain is uniquely their own and deserves respect.
You say you have tried lots of things and worked with many therapists. What I don’t know is if you tried any one thing or stayed with any one therapist long enough for it to have maximum effect. You need long-term, on-going support, not a desperate move from one intervention to another.
I urge you to give therapy another try. If you think it isn’t working, don’t drop out. Stay and work through why you think it isn’t working. Such conversations are sometimes the most valuable ones in therapy.
You might also find it useful to join a forum here at PsychCentral in order to have the support and guidance of other people who are struggling with the same issues.
I wish you well.
