This is something I haven't shared on this forum yet, but after reading your post kris, I think I will. My sexual abuse was also by my brother, and it lasted for several years until my family cut off contact with him, and that was when I was 12 years old. I bet you wouldn't look at me and tell me I'm the weird freak who did things like that with her brother. I know that things like this are especially difficult in many ways. For myself (and this doesn't have to be the same with you) I am feeling the way you do because number one, he was my older brother, I kept trusting him and going back to those situations. Also he was not an adult himself but only 6 years older, and lastly incest has a HUGE stigma attached to it. I often feel intense shame when topics like incest are brought up people joking about "redneck, white trash incest people" and I feel they are speaking about me. I feel shame because of this because I feel like I committed incest, even though I was a child, and I didn't know what I was doing and he did. But still I feel the intense guilt and shame, and I can't seem to put the blame on him. But this is the ultimate goal, to remove the blame from yourself. I'm also trying to do this.
My therapist was also extremely confused and frustrated, and even admitted later on that "she thought I was just trying to be difficult, but now she sees that I really am confused" So I feel like I'm in your spot as well. Good for you for standing up to yourself and saying LOOK I'm coming in here every week, I want to change!! I kept going back also even though I am like you. I still can't get past seeing myself positively but this doesn't mean I don't want to change.
Its the opposite actually, you want to go to therapy to be able to learn and get through these issues SO THAT you can start seeing yourself positively. Its a goal to work towards, with many things that need to be addressed along the way before that goal can be reached. Keep drilling yourself with the phrase its not my fault, and try to do anything to hold on to this thought even if at times it barely hangs on by a thread. I'm in your position right now, so I can't tell you what you will need to do, but the hanging on to the one part "intellectually" that I'm not at fault, helps, the emotional and rational sides will eventually join in and I'll begin to believe it. It takes time but your first step is going to therapy and wanting to take the right steps to feel better.
But don't say that your a freak, I know exactly how you feel COMPLETELY because I feel the same, and it won't go away overnight, but trying to let go of this negative unhelpful feeling towards yourself is a big part of the process, and it is a gradual process so be patient. I hate being patient also. Your emotions are strong, and the ones that you feel like your a freak, means your blaming yourself, and feeling sick about yourself, and this is what the therapist you are seeing should be confronting instead of saying "oh that must mean you don't want change....." NO.... I think you need to speak to him and say what you said on here, that you want to get better and get past these feelings but you need help about HOW. And only then will things start to progress. Therapy is very complicated both for the client and therapist. before getting work done you first need to both be on the same page, with the same goal. Then you can work on it together, instead it seems like you and him are off on different tangents and not communicating or working in synch.
I wish you luck kris feel free to message me sometimes, I see you and I are actually going through extremely similar situations, if you ever wanted to speak to someone who relates to your specific issue.
