Please don't cut. It's not a good coping mechanism and it can end up causing you more stress rather than reliving it. The relief you get from it is very short term and many end up developing an addiction to it, leading them to cut deeper and deeper, sometimes to the point of permanently injuring themselves. Cutting scars also aren't that easy to hide, especially since, depending on how deep you cut, they can end up bulging from the site of injury. That's not getting into the fact that cutting generally requires a lot of aftercare, especially after deep cuts in particular, and sometimes may even require stitches. I wouldn't recommend it.
