Caring for a friend with clinical anxiety?

So I am 27 and I recently fell into the trap of unpaid carer. I’m shopping cooking cleaning and basically trying to get my friend to be independent again.

Any tips on controlling their worries so I can go and get just one night’s rest.
Never done this before. My paid job is full tine support worker ahd I come back to more work.

Anyone got any tips on people with anxiety? :-???

Sadly, the more you do the less he has to.
You MUST look after yourself first.
