I want to take this wristband off and cry to my mom to help me through this depression and show her

But my friends, will she tell me not to hang with them? It's not their fault, I've been doing it scince before I met them, I just ticked off my cat so she would scratch me so I could blame her for the scratches. But I only did it so I could have my wrists cut up. Now I have sharp things in my room that I have utilized. my leg is scratched up. my arm is still bleeding a little. How do I tell her without her freaking out?

This is very serious. What you are describing is called "Cutting". People who cut themselves do so because the physical pain they feel from cutting is more tolerable than the emotional pain tearing them apart inside. You need professional help. If there is another adult you trust tell them what is happening and ask them to go with you when you tell your mother. It is imperative that you tell your mother. If there isn't another adult you trust to go with you then this is what you do. Ask your mother to sit down with you because you have something very important you need to talk to her about. Be calm, but insistent. Let her know how much you love her and respect her and how much you need for her to listen to what you have to say. Ask her to promise not to get angry or upset or you won't tell her what your problem is. Once she agrees not to get upset, explain to her the emotional pain you are experiencing and tell her you need her help dealing with it. Only then should you show her your scars. Tell her you want to stop hurting yourself but you don't know how to do it by yourself. Then look at your mom and tell her you need her help. Hold her hand when you talk to her and look her directly in the eyes so she will know how important this is to you. I know how scary this seems. I know you think that she won't understand. And she probably won't at first, but if she loves you her only concern is going to be your well being. If she blames your friends, which she might do, just calmly look her in the eyes and tell her that your friends don't know that you cut yourself and that you started doing it before you met them. Then tell her this isn't about your friends it is about you and you need her help to get better. I don't know your mother so I can't predict how she will react, but, I know from personal experience how difficult this is for you. I was sure my mom would freak when I told her what I was doing to myself. She didn't freak, she cried. She pulled me into her arms and cried deep, heartwrenching sobs and told me she would always love me and she helped me get the professional help I needed.
