Disabilities causing suicidal thoughts

I have several disabilities and don’t see the point in being here anymore. I always feel so useless and worthless because I can’t work and my impulse buying has got really bad to the point I can’t keep my own cards anymore, I am dependant on my family which makes me feel even more useless and guilty. I have no structure and purpose to my life and spend most of my time alone stuck indoors, but there’s nothing I want to do. I have tried to get so much help over the last 10 years and nothing has been helpful so I’ve given up hope. I’m always fatigued, have no energy, in pain and stressed out my mind 24/7, my head doesn’t shutup and is constantly racing, and I have panic attacks whenever I have to leave the house. I don’t see the point in suffering anymore and no one seems to be able to help me.
