sorry you went through that. Im not always comfortable with certain type of people either because they remind me of my abuser. one thing my treatment provider said to me helped a lot in this kind of situation where I am alone and someone says something....

do some reality testing. going to use your post so that you see what I mean...

in your post you stated

you and this person were the only ones in the store where you were.

then you said he stated what he did

then the words after that is ... "I don’t think he saw me. "

reality question.... if he didnt see you and you were the only one in that section of the store who was he talking to? not you if he didnt see you.

reality.... thee is nothing to worry about you were completely safe since he did not see you so he wasn't talking to you.

after he saw you, you said he gave you a creepy look.

reality question was it a creepy look as in he wanted to hurt you or a creepy look that meant he was shocked you were there and might have over heard what he said.

my reaction in therapy wow yea your right I was safe. this was just me being a bit paranoid and hypervigilant (PTSD symptoms in me) and yea that creepy look could have been he was staring at me because he was shocked I may have over heard what he said. for me it was a scarey situation and due to my PTSD I may have misinterpretted what was going on.

After gonig through the situation with my therapist I felt better and realized that if the guy didnt see me he could have been talking on an ear headset for his cell phone to someone else, he could have been talking about the merchandise he was looking at or for in the store..... so many things that he could have been saying this about other than me since he didnt see me there until ....after.... he had said what he did.

suggestion maybe print off your post and take it to your treatment provider who can help you work through this and find ways to help you for the next time something like this happens.
