I'm the same.
But i must advise to try not avoid things.The more you avoid things the worse they get.
I cant do any of those things got to the point where i never stepped out the house.
I now have a support worker and gradually we are able to go out together once a week.
its a long process and your write it takes alot of willpower.
try bit by bit.for example: Go up to your garden gate every day then venture a bit further the next week.Eventually things will be able to be enjoyed.
A therapist may help but what i find helpful for me is my support worker who visits me weekly and takes me out the house.

wishing you the best
