Wow,
You're dealing with a lot. However, I see that you are a fighter.
I would drink a lot of juices instead of supplements to support the body and mind. Himalayan salt with water might be an easy drink for you to make to get the minerals into your body.
A nice walk outside might help you a lot to get the needed fresh air and get a break.
Think positive - you're going to get thru this. It will only get better from now on.
I can help you even more, if you like. I would need more information.
