When I was a small child ,, 5-6 years old. My cousin sexually abused me. And when I was 12 years old, my younger sister died. All these things have been bothering me so much. Sometimes i can't even sleep. Many times I have dreams that someone wants to kill me or I am eating a fruit, and insects are coming out of it, And once I saw that I am cutting my hair with scissors. I am not able to stop myself, I am very upset and because of this I have problems breathing many times. Is it PTSD ? Please help me
