I'm a non-smoker and have the same problems. I'm not sure how much is normal, how much is poor memory and how much is PTSD.

I mean, what is normal for people to remember?

Very recently like 6 weeks ago, I suddenly remembered right before a therapy session that I once saw a male therapist one time. I saw him because I was being sexually harassed (not severely) and because this guy had a bad track record and before it escalated I was sent to a therapist by my employer as part of there employee assistance program. This happened maybe 8 years ago?

I had completely forgotten, and I can't even remember the nature of the harassment, but - and I'm not downplaying it - but I don't think it was that serious which is maybe why I forgot.

Anyhow my T said that when people are traumatised, and subsequently under even normal stress they can forget things quite easily. The reason being is we tend to have tunnel vision or she likened it to a deer in headlights we are stunned by the light and can't see the car, the colour of the car, or the forrest around us.
