I'm so sorry, dear Have Hope.
It really does seem like there is too much to solve! You're not superhuman. I'd definitely try to narrow things down.
Just as an example, you might feel more secure if you decide to stay in your relationship for now. And the eating disorder... That (sadly) isn't going to go away overnight.
It's the same for 'dieting', too, imo.
You don't need to worry about any of those things right now. You can let them go.
Possibly, this is what your therapist will say; start small.
Big hugs.
