You poor thing 
Sounds such a massive amount of stressors to be up against, whilst battling 2 really painful and debilitating physical conditions as well.
(You won't believe it whilst everything must feel so bleak, but, truly, you deserve so much admiration and respect for just functioning day-to-day.
To have also had the courage to leave a hellish relationship, and be coping with the fallout from changed circumstances, probably makes you question whether it's all worth it?
YES IT IS.
You have done a wonderful thing.
For yourself, and for your kids).
