My parent told me something about my sibling

Hello everyone,

I've been working through my OCD with a Psychologist for a few years now. I'm doing great! Which is amazing. I will warn those who are reading, this involves sexual assault, so please be advised.

However my parent told me something about an older sibling that happened back when I was only a toddler.

My sibling was apparently SA'd when they were around 10 by a stranger, and apparently I was in the room. I would have only been 2.

I don't remember anything, and as far as I am aware I was spared. However we all know what OCD is like.

I feel sick to my stomach by this news, and I'm a little upset with my parent for telling me. I don't know what to do, I'm worried this is going to mess me up, especially because I have been doing so well.

Has anyone else been through something similar that can shed some light? Or give me advice?

I am unable to see my psychologist for another 6 weeks.
