Am I overreacting?

So, besides being emotionally abused by my grandmother, who would drink to much and then tell me how worthless and stupid I was, I think I may have been sexually assaulted by her as well.
I developed early and my grandmother would often insist on looking at me naked to see how I was developing. She would sometimes touch my body as well and make comments. I don't think she got any sexual gratification out of it, but it still made me feel really embarrassed and gross.
I don't know if I am being a drama queen, but it still effects me. It effects how I see my body and it effects my ability to have intimate relationships.

Am I overreacting or was she wrong for doing that?

Absolutely NOT overreacting! That is abuse and should be seen as treated as such. Have you ever sought help for this??

You are absolutely NOT overreacting, and yes that is considered sexual assault/abuse. It is understandable that it affects your body image and ability to have intimate relationships; that part of you has been wounded and scarred and you have not healed from it yet. I would suggest seeing a counselor for this, especially since it sounds like you have some insight into how it's affecting you. And we here at PC are also here to support you

That is abuse. I'm so sorry to hear this happened to you. It was not okay.
