Your question is a reflection of my own at the moment, Lonely Chemist. I struggle with depression and anxieties, I would like be a counselor, but do not know if it is something I am honestly capable of.
I have a read a number of your posts and find them rather well-written, charming and delightful. Have you considered perhaps taking a creative path with medical knowledge? Though it isn't the same as saving a life in the E.R., storytelling has a great ability to heal.
