Ivy , I agree with Bump, you have been through so much. I also wish I had all the answers im glad this thread has been support for you.
The Icarus trust posts here a lot too.
I also admire your strength though this difficult time and you are right to concentrate on your own health and well-being. I hope and pray your son will seek the help and support he needs. Take care.
Bump- I’m finding the long covid is affecting my breathing, cold weather is also making it worse, so i can’t walk much either. But I think the stress and anxiety doesn’t help. Take care of yourself too.
Thinking of you all
