It does nothing but makes it worse. You are hurting your arm by inviting germs in.
Talking to someone works best. Never self-harm. If you feel like you need to talk to someone (doctor, etc.) And bullying and depression is the main cause of this.
I hope anyone who cuts gets better soon and is happy again.
OMFG THANK YOU. I have had endless battles with fucking stupid 12-year-olds trying to convince me that mutilating themselves "helps them feel better". No, the only thing is gives you is scars and shame.
It's not cute, cool, attractive, or useful.
I hope society squashes the emo out of those idiots some day soon.
