Sorry you are feeling this way at the moment. Thankfully feelings change. I think it would be good for you to keep account of things you are achieving.
We take for granted that we still are functioning, getting dressed, doing the washing up etc these are achievements. But I do understand that you are looking at the things you cannot do.
As regards your friends, I can appreciate that you do not need rejection. But the saying is true, good friends are there for you the rest are not friends.

I have fairweather friends but I accept that they cannot deal with the new me.
Mb things have changed for them too, they have lost you as the person you were.

Try something new that you can do. It may be slow work or a project but something is better than nothing.

Lots of love, keep in touch
