Please do talk to your team. They are healers, not judges. They are there to help you deal with your feelings and learn from your experiences.
Clearly, it was in no way your fault that a man touched you inappropriately and said terrible things to you when you were so young. It’s very fortunate that it stopped with words and some touching. The fact you can’t stop thinking about it now tells me that you were profoundly affected by it and that you need some help processing it.
My guess is that the incident at school felt like a repeat of what happened when you were 12. You were frozen in fear and didn’t know what to do in both situations Your therapy should help you forgive yourself for being scared and should focus on developing skills so it doesn’t happen again.
As for the other two events: Part of your therapeutic work is figuring out why you let yourself get into dangerous or inappropriate situations and learning how to love and take care of yourself. Your team can’t help you do those things unless you find the courage to be honest with them and fully engage in treatment. I hope you will. You’ve begun the important work of treatment. Now take it to the next level so you can get relief.
I wish you well.
