You are me... doesn't that sound strange. I waas a cutter too... about 20 years ago. You are NOT alone. I had suicide dreams and fantasies and was always cutting myself when I would get agitated or angry or upset. Years later I realized that for ME cutting was a way to show myself (and everyone else - even though I never really showed anyone) that NO ONE could hurt me as much as I could hurt myself. I am now 35 years old with two teenagers of my own. Those years in high school were the most difficult of my life. I was a mess and I felt very displaced I lived with various family members which just made it harder. I am sure that is a lot like living with one parent then the other. Do either of your parents spend time with you? Do you spend most of your time alone? I wish I could reach through the computer and put my arms around you. I remember being afraid all the time. On edge and not really comfortable in my own skin. Mostly like I just didn't belong.
I had a family member finally take me to counsellor. I was so mad that they took me there... several weeks went by that I didn't say a word. Just sat there mad as heck that I was there. I had to go 3 times a week after school. I was uncomfortable and ashamed and I WAS NOT going to talk to this guy.
Guess what... I did. Now I can look back and see what he did for me. He really helped me make it through all of that.
I'm here for you.
