Oh (((((((( selfy )))))))))) Looks like you could do with a big hug.

I might be wrong but it sounds like you were using the cutting as a way of blocking out feelings? If you find that the feelings are too intense replace the cutting with something else for now. Holding ice-cubes wrapped in a tea towel can do the same job but without causing any harm.

If you are swamped with negative thoughts you could try to use distractions such as listening to loud music, doing a crossword puzzle or computer game.

Be gentle with yourself.
