I'm sorry you are going through this, Julia. I'm relieved to hear you are getting medical treatment again and it's helping. I know lots of people want to go off their meds and have the same experience. It must be a tough choice to make.
I can personally relate to running into people, seeing the same streets, etc. I believe I started a thread called "geographic cure" on here that you may be able to find. It's not that I'm timid, feel guilty, etc. Not AT ALL. What I do feel is sick to my stomach when I see the places and faces related to (on a good day) the worst time in my life, or (on a bad day) the mental/physical abuse they systematically did for years and totally got away with it. It makes me relive the traumas.
I cannot believe how freeing it is to be in a totally different locale. I don't know if that's an option for you, and it isn't a substitute for healing, but it did help me. Shouldn't be necessary, but for me personally, it is. IMHO
