i think...

dbt would be terrific for you.

you would learn skills around
-mindfulness meditation (to help you feel more relaxed)
-distress tolerance (when you start to feel really bad)
-emotion regulation (so you learn to soothe yourself)
-interpersonal effectiveness (so you learn to better manage your relationships so you get on better with people and get more of your needs met)

i would ask your p-doc about whether dbt may be a possibility for you. empirically... after one year of treatment most people show a significant improvement in their functioning. empricially... it has been shown to be the most effective form of treatment for the sorts of problems you have.

i really think that would help you out significantly so you are more stable and are better placed to get what you want to get out of life.
