I need help.

I haven't cut for almost close to half a month. That is great and all, but the urge has been eating me away. Especially today.
Today I found myself gently rubbing edges of things along my arms and wrists. I have been under a lot of stress lately, my friend is in trouble and is mad at me, so I can't help her. My family has been unsupportive of me. My brothers are being complete douchebags. The only thing that has been getting me through the days are the thoughts of all of you guys on here. I need help. Please. I love you all.
