maybe you can write a letter to the person? it would likely be much more productive and worthwhile than confronting them. confrontations, especially when you feel unable to really express yourself freely and don't feel safe, can be a major setback and a revicitimization. probably NOT what you need right now.

if you write a letter, give yourself permission to express all your deepest feelings, no matter how intense and or negative. just let it all out. and maybe show it to your T or to a trusted friend if you want to feel more heard.

this might help you process some of the feelings you have without revictimizing yourself.
