Try to restart yourself. I can totally relate to how you feel. I was in an severe accident some time ago, and went through 2 years of rehab. I had plenty of time to think, and I just wanted to die. I was in such pain, no painkillers would work over such a long time, and I would never be able to get my old life back. Anyway, my goals and expectations naturally was set back to zero. I can tell you it works. The lower expectations, the greater small pleasures and wins. It's a lot of mental work, and I had a great team helping me. But in the end, I was the one who had to put my head in a right place. It's like everything else in life, you have to practice, train, repeat and repeat. Talk to yourself in the mirror, say it out loud. Keep repeating in your head as often as you can. Eventually, your mind will be convinced. After this accident, my mental health problems almost disappeared. Good luck and lots of loveS
