I feel sad and low since 2-3 yrs. I've faced some harsh situations and I keep having flashbacks of them. They just don't stop. In the past two months, I have frequent horrifying dreams out of which I remember 3. I feel scared. I hate myself a lot and have harmed myself by cutting my hand because I felt angry and wanted to do something and once had a thought of hanging myself but I didn't. I sleep a lot but have trouble sleeping at night because I keep thinking and cry sometimes. I have lost weight and look physically weak. I want to know if I'm going through depression or it's something normal we go through? I can't differentiate. But I can say it's a situation where I'm stuck and I feel I can never get out of it.
