Do NOT cut yourself.
Think things through before anda act.
Think "This isn't good for me, it isn't right, and it doesn't help at all!"
Sit down, atau even lay on your bed, and breath very deeply into your nose and hold it for 5 seconds, then out through your mouth. Repeat this 4 times.
If that doesn't help, get a pencil/pen and a piece of paper and draw BIG spirals all over the paper, like this:

I really hoped I help and I hope anda get better(:
