possibly triggering

I haven't cut for two years but when I'm stressed or craving it really badly it's like I can feel it. I feel either past cuts or anywhere else I want to make a cut. I either feel that sort of general pain that you sometimes get after cutting or I'll feel the sharp sting that the blade makes coming across the skin. Sometimes I taste the blood in my mouth or feel it clotting in my throat. I know it's not real and t makes me feel really crazy sometimes. When I'm really stressed it just won't go away. it's like I can't escape it. I guess I just want to know if other people have experienced this. It makes me feel really alone and psychotic right now.
