Typical anxiety or a more serious MH problem developing?

[Eyesdow]

I've had anxiety for several years due to past DV. I was also diagnosed with PTSD but my then-therapist thought I'd recovered from the PTSD after finishing EMDR therapy one year ago.

Something I've become aware of lately is how nervous (and I dare say paranoid) I am when I'm outside alone.

I really hate having to walk past men if I'm passing through a quiet place, I almost always have to look over my shoulder once or twice when I pass them to make sure they haven't stopped or are following me.

I get antsy when vehicles pass me if I'm walking near the curb, I have intrusive thoughts about being hit somehow.

Am I losing the plot or does this just sound like harmless anxiety?

Didn't want to leave your post unanswered, I don't know but for me my anxiety was and is not harmless. If yours is affecting your behaviour in that way then I think you need to address it more fundamentally.
I don't think most people feel that way about vehicles (although I personally agree about the man thing).
I don't think it's ever a waste to seek help for mental health.
