A constant fog

When I was growing up I was molested by my older step brother. I remember for years he would tell me to do sexual things to him and force me to do these things, I would tell him no. He told me that if I told anyone his dad would leave my mom and my mom would go to prison for life. At the age of 12 I refused to be alone with him EVER. I started staying with my grandparents and one day he came over while they were at work, he pushed me on the bed, held me down and shoved his hands down my pants. He would hold me down and abuse me while our parents were at work, but I kept it to myself. I don’t even know when it stopped, I feel I have suppressed ALOT of these memories. Recently triggers have arisen and now I am unable to stop thinking of it, I feel like I’m searching for memories that aren’t even there. Have you been in a similar situation? What did you do? I have been diagnosed with PTSD, Bipolar I disorder, and GAD. How do you deal with triggers and what advise can you offer? All of these memories are just a fog.
