(((Jen))) It sounds like your docs need to update, add to, or change your meds somehow. And I always recommend hunting for a good therapist. Ask around about therapists in your area.
And that diverticulitis. You poor thing. ((hugs)) I have ulcerative colitis and when that flares it makes about everything else more difficult.
And don't forget to baby yourself and do things that you like to do, whether it be soak in a bubble bath or watch a good movie.
I'm sorry you feel so bad. It will get better.
