Welcome justducky81! I'm sorry to hear that you were abused by your cousin, abuse at any age is very devestating. Our family has been touched by sexual abuse at the hands of our father to my sister and me. It took years for me to reveal this truth to anyone and once I did, I felt a giant weight lifted off my shoulders. Congrats to you for speaking to your therapist to begin the process of healing, just getting it out can be so therapeutic and helpful.
One of the beginning steps I found helpful was to forgive. Not because they deserved it, but because for my own self preservation, I needed to get rid of the anger, bitterness and rage inside of myself and that only happened through releasing our father through forgiveness. Every time I thought up the atrocities of abuse, I consciously made a choice to forgive and let go of the hurt and pain. At first it was VERY HARD to do, but over time, it got easier and easier as I made it a habit. Trust me, you are NOT alone! There is HOPE, I found mine in handing over all my junk to Jesus, who knew all my pain better than I did and knew how to heal it and make me whole again.
I pray you find peace, strength and hope in the days to come. Do you have a trusted friend you may confide in as well? Someone who could come alongside you as an accountability partner to check on you as well as help you through the process of forgiveness if you choose to go that route? It's tough, but very doable. Keep your chin up... it's a process. I'll be praying for you!!

I have had similar abuse. I was sexually abused by a grandfather, when I was 9yrs, I have a scar of a cut and a cigarette burn, no memory of how it got there, my mother left my brother and me with him. He was abused by my step-uncle. I was later raped at 12 yrs by a Male babysitter who was my dad's friend's son. I was raped by the brother who was abused.
I have, ocassionally and lately, been having flashbacks of those things that happened and felt very uncomfortable in my own body, like I feel gross and disgusting and need to shower and cover my body.

I was sexually abused by my sister when we were children, so yes, I totally get where you're coming from and no, you're not alone. About 3-4 months ago, I got the courage to confront her about it, I asked her why. She didn't have any idea; apparently she hadn't been abused, she just got the idea from friends and did it because she could.

For me, finding and unburying my anger was very useful, a lot more useful than just "forgive and forget." Constant forgiveness is what's been keeping me trapped in place, in a very unhealthy family dynamic, for my entire life. Finally letting myself feel how angry I am at them is what's FINALLY letting me break free from them and start a real life for myself. It's letting me choose myself, instead of feeling obligated to care for my abusers forever. I'm not saying that you should let anger turn you bitter, just that forgiveness isn't always necessary or useful; for me, it is detrimental.
