Is there a reason you can't have a pet? It might be a wonderful comfort for you. With financial limitations, or if you have allergies, I could suggest a rat! I've had them in the past and they are sociable, low-maintenance pets. These days I have an elderly rabbit who loves to be held. Since I've been making an effort to hold and pet her for an extended period every day, I find that it's at least as comforting for me as it is for her.

If possible for you to volunteer at an animal shelter, that's another good way to get a nice stress-reduction "fix."

Like many others here, I totally relate to and sympathize with your frustration in dealing with doctors and trying to get a diagnosis. Wish you the best.
