I found yoga great help for chronic pain and overall very helpful for mood.
Even better is signing up for a set of classes locally--people are nice,
you get good information on positions, etc., and it is a kind of "social life"
for me as I am isolated too.
No matter what state you are in physically, you can do yoga.
There are always modifications for each position.
When I started I was like a rusty deck chair and couldn't turn my neck to back up my car.
After a year, I could move my neck freely and put my palms under my feet with a straight back.
Pretty good for someone who was over 50 and sitting at a desk for years.
More importantly, I felt so much calmer and at peace.
There's lots of videos free online too if you want to start that way.
Bottom line though, is that someone is draining your life energy and peace
and facing that will eventually need to happen.
You deserve to be happy.
