What to do if i am 36 and suffer severe mental illness, suffered a hard life , ive lived alone in a council flat for 9 years and this is something i can't decide?

Hopefully treated?: Long term supportive therapy and being part of a support group is also really important for a lot of people; doing volunteer work among other things can also help a lot. Of course, hopefully you've had a proper evaluation and see if medications can help. If you are so anxious you can't leave the house, tele-medicine can be great to get help if no one can do home visits. Call local resource line.
