I was wondering if anyone has advice on how to tell a PCP about PTSD.

I have a new resident who I went to see last week and ended up freaking out when she went to examine me. (I hate being touched as it causes flashbacks.) I was just expecting to get some test results back but that was not what happened and so I was not prepared. Given the medication I am on she knows I have mental health issues, but the discussion of my medical history (for some reason?) did not include any questions about my mental health. The reason I am asking is because the time I told my last resident about my SA she practically ran from the room as fast as she could and didn't look back. While my new resident seems to have a much better bed side manner than my last one, and totally picked up that I was freaking out, I am scared to have the same reaction again. It is hard enough to talk about, but then when I have to deal with these reactions from someone who it seems should be trained just makes it harder the next time.

Thanks for advice.
