"I swear, some people just see a gentle, sensitive soul and seek to only destroy it. It gives them power that they can't muster up for themselves."

I find this too....I am destined to be in grade school for the rest of my life...

About your ex. You had a good rant here..If it helped you, can I suggest you write your ex a good long scathing letter? On paper. Simply write down how he makes and made you feel.
Oh I am not suggesting that you send it, but the act of writing it might help you release some of your thoughts.
You could even burn it like they do on television...but personally I would write pages and seal it in an envelope....Just knowing it was in my drawer would give me a small sense of closure. Metaphorically putting him away...

Umm..can you change doctors? We don't need to be told anything negative IMHO...
