Have you considered working remotely? There are a lot more remote positions available these days than you may think.
So, in the larger context, TAKE CARE OF YOURSELF, FIRST. BEFORE you work on your work environment, make sure your home environment is safe and restorative. (And, these days, has a fast enough connection.)
All else will come from this. Remote work. Or, when that's not possible, simple relief from stress when you are away from work.
TAKE CARE OF YOURSELF, FIRST.
