Incest Survivors Support Group
Incest refers to any sexual activity between closely related persons that is illegal or socially taboo. Consensual adult incest is very rare. Incest between adults and prepubescent or adolescent children is a form of child sexual abuse that has been shown to be one of the most extreme forms of childhood trauma. If you or a loved one is a survivor of incest, join the group...

Did you have evidence or? How long did it take for them to convict him?
Someone once told me that home should be a safe place. That helped me lift some of the shame I was carrying and be a little more able to provide some compassion for myself. It's true. Where you sleep should be a safe place.
I think the fact that you told the school counselor was very brave. Both you ladies in this discussion are very brave.
I know this may sound trite, but can you try your best to not worry about him getting out of jail just yet? My therapist often has to remind me to "cross that bridge when I come to it". I too was fearful the abuser would come kill me after disclosure. She reminded me that murder is a separate crime from incest/molestation.
Hyper vigilance and wanting to feel like you have some control over the future is a normal reaction to not having a safe home environment. You are likely a very highly aware individual because of it.
Thank you for sharing and welcome. I hope you find this place as safe and as helpful as I have.
