These people usually have nothing wrong in their lives, though some of the times the attention cutter will start due to a feeling of sadness caused by:: 1) loss of all friends. 2) parents don't ever pay attention to them at all. 3) feels like a nobody. 4) feels like everyone hates them. 5) feels like a total outcast. 6) e.t.c.
in most cases, when people feel so ignored and lonely, they'll start to think that the last resort is to cutting themselves, in order to have people to care for them.
sometimes, the attention cutter will be ignored once more, after people find out they are cutting for attention, and sometimes when the attention cutter feels so much pain of being lonely and ignored, they'll transform form to an attention cutter, to a real cutter.
this is why you shouldn't ignore them, instead talk to them, and ask why they are cutting for attention, cause there was always a reason in the first place, and completley pushing these people away, will only make matters worse.
"Omfg, guess what Beth keeps doing."
"She fucking keeps showing people cuts on her arms all over the school."
"Gross. What an attention cutter."
"I know. This is why we choose not to friends with her anymore. She always needs attention."
GOOD WAY OF HANDLING THE ISSUE:
"Beth I know you're cutting yourself for attention."
"What made you think that?"
"I know what you're parents are like."
"You know we can talk about it if you want?"
"Why do you give a fuck."
"Because I care."
