What is it giving you the urges to cut Soph? You say you've been craving it for a while but on Saturday you came really close, did anything trigger it? Avoid any temptations and that means getting your mum to put the knife somewhere else; and it means you will need to not look for it again. Distract yourself when you have those urges.
Furthermore, said friend is unlikely to be "disappointed" that you cut, more concerned for your general wellbeing. You know self harm, specifically cutting, is just a coping method for what is going on in your life, can you tell us a bit more about what you think cutting would
help you to do? Then, we can give you other ways to beat the urges.
On that note, an excellent link is "
What to do RIGHT NOW instead of SI ", which might be worth reading and taking careful note of, as you can match your feelings with appropriate actions, and relieve your urges to cut.
Please keep talking to us; we're here to get you through this.
