Why does my girlfriend cut herself?

You'd need to ask her about it honestly.A lot of people turn to the wrong habits to fix things in their lives, or to make the pain fade. It's a terrible thing to do, and it doesn't help in the long run, but in the moment, it may feel like it's helping. Try to be there for her, but don't let yourself get dragged down in the process. You may not feel like you're doing enough to help, but you can't imagine how much it helps to have someone be there for you and love you when you're hurting like that.

The best thing to do is to talk to your girlfriend, and support her wherever you can and let her know you're there for her.

That, we can't possibly answer for sure. Self-harming could be due to countless various reasons, even ones that doesn't make sense to others. The only way to know is either to ask her. Don't jump to conclusions even though you've caught glimpse or hints of possible causes. Ask,

Sometimes people hurt themselves for often very strange reasons. Every person who hurts themselves has their own reason. It's never the same, but there are some commonly known reasons. People can hurt themselves to see their own blood, or to get the image, the pain (often to 'fill emptiness'), ... If you're really concerned, talk to her. :)

People can self harm for so many different reasons.. Maybe she's going through a tough time or it's something a bit deeper than that.. For whatever reason it may be you should think about talking to her about it. Letting her know that you care & that you're willing to be there for her in any way she needs you will most likely really make her feel better. I really hope things get better for her, my heart goes out to her :)

There are many reasons why people self harm; and there is no way that I can tell why exactly she does it. You may need to have a chat gently to her about why she does it as there are plenty of reasons for it.

Self harm is a coping mechanism and unfortunately many young people do this, just like your girlfriend. Often there's more than one reason but it's often to relieve tension, punish oneself, feel more grounded, or legitimize feelings by "matching them" on the outside. I hope she gets better.

There are many reasons why a person decides to self harm. Try and think of all the possible reasons why this is happening: has she gone through loss? Has she been effected by an experience of any type? However don't jump to conclusions, instead try asking her.

Sometimes people see it as a control or a release. It is a kind of pain they can control and a release of emotions.

There are a number of things, she could get anger or sadness relief out it, she could be doing to make scars, she could be doing it to get a "twisted" version of entertainment.
