What can I do?

3 years ago I had a major stroke at 51, which I partially recovered from. Then I had another stroke, in June of this year (2021). This left me shattered emotionally. I'm on 2 different anti-depressants which do nothing. Then I was starting on Baclofen. This sent me into a deep depression. I suffered from daily intense anxiety attacks, So much so my anxiety and depression got to the point I went to the ER. Doctors (Including my own GP) try to help but no combination of drugs did do anything for me. I am overcome with feeling of regret, all the things I never did, never will do. Now it is too late. No Wife, No Life, No Future, No Hope! Became my mantra. I know I am a bitter loser with nothing. I began thinking I didn't deserve all the things most people took for granted. I have no friends, no relationship, nothing. I have decided the only thing left for me is death. To hasten this end I have all but stopped eating losing a pound a day. I also stopped taking all of the medication antidepressant, anti-anxiety, anticoagulants, high blood pressure, diabetes all of it.
I'm just sitting here waiting for another stroke to kill me the sooner the better!
