Aww, bless you. I don't know you but as a mom this pulls at my heart strings.
Did you not have anyone to go with you? It was very brave of you to arrange all this & show up.
Just so, so sorry it turned out so traumatic. There are other very good docs out there so please don't give up.
Maybe at school you can see a counselor & get some advice on what to do next.
Have read some of your post & maybe being back at school will give you some structure & peace, I hope so.
Keep plugging away, it's worth it, I promise.
Take care of your self.
PS. Love your music.
