Your 2nd post says you try to occupy your mind with full time work and full time school. That is very admirable! You have a lot of ambition! Along with that you have doctor's appointments and physical therapy. I wonder if it is all too much for you though? I think sometimes the mind needs to be unoccupied to be free to reflect and evaluate things in your life.
What kind of counselor do you see? A counselor through the school or someone outside the school? Could be the therapy you are in is not right for you. Think about trying psychotherapy and see how that works? It is more in-depth than some other types of therapies/counseling. It is very interesting.
I hope you find some permanent relief for your physical pain and your depression.
