I've had the experience of reading a checklist like that and being shocked to find I fit almost every item on the list.

It's very common to feel your experience is less of a big deal than other people's and that you shouldn't be posting - it's a kind of survival mechanism that tells you it wasn't so bad, and a lack of confidence and self-belief, but it's not true. There's no competition about who's had it worse, if you want to post then you should.

I can't tell you if something happened to you - I can't know - but it's possible. I would strongly recommend therapy, because then you can work through these worries, feelings, etc, with someone trained to help you.
