Why does my girlfriend cut herself?

You can't know for sure what's going on in on other persons head, you can never know another persons story from beginning to end, you can not see things the same way another person perdices it, so there is not a solid answer to this question, only your girlfriend knows the answer.

It can be for many reasons, sit her down and talk to her, you are really worried about her and she does need help. You just need some understanding about it but it probably wont be your fault

This question should be answered by her best, but you should know her enough to understand why and encourage her to seek help. Cutting is having the control of the one thing that you can control, your body. I should know, I once was self-abuser. I had no control of what others did to me so it made sense to a broken mind. Loving encourage her to seek help.

A possibility of a personal complex or she might be unhappy with an unchangeable situation.It may be that she is trying to draw attention out of loneliness as well.

Self harm is different for every individual and your girlfriend's experiences with it may be different from my experiences. But for me, it used to help calm me down before I went to bed and it would get rid of my headaches. It became addictive and I would suffer more not doing it than I would if I did do it. I found a comfort in being able to control that aspect of my life, or so I thought. Truthfully, self harmers, if anything, lack a lot of self control. It made me feel better and I felt like each cut calmed me even more, and each time something upsetting me, left my body for a short while.

There are many reasons why someone may cut themselves. Sometimes it is because they feel numb and want to feel the pain. Sometimes they may feel that they deserve to be punished for some reasons. Sometimes it is a way of expressing an emotion like anger or frustration. It is hard to tell without asking the person themselves what feelings they are experiencing that lead to self harm.

she may have suffered from something traumatic. no one knows why except her. some people cut because it makes them feel like they have control of the pain that they feel inside.

It can be an emotional relief for people. They either focus on the pain, the blood, or even both. It can even serve as a reminder that they're still alive and not just a fading soul.

Maybe she feels a dark void in her heart, a lot of people go through problems that are left unspoken, and it's hard to express what you feel to someone who hasn't been through it, it could feel like talking to a brick wall. So sadly she takes the anger, hurt, blame all these feelings combined and hurts herself. A form of escapism. Escaping her mind, her demons & her problems. It's sad. But there are many reasons for cutting yourself. Sometimes there is no reason. Sometimes we just do it because our minds are enslaved by thoughts of being unworthy of love?

She is probably feeling pretty bad. When feelings get overwhelming some people cut themselves. For some it "releases" some kind of tension or built up jumble of feelings. That gives a momentary feeling of relief. For others they might be doing it because they feel like they don't deserve anything better and therefore hurt themselves because they don't really love themselves. They might struggle with a lot of self hate. I think for most it is a coping mechanism.
