My GF just told me she hurts herself...

[Altiier]

It started when she burnt her finger on her curling iron, now she burns and cuts herself... fucking Christ i'm going to be sick... What do I do??

Tell her that you love her. Tell her how much she means to you, and how much you care about her. Tell her how beautiful she is.
Also try to ask her why she hurts herself.

Tell her that you love her. Tell her how much she means to you, and how much you care about her. Tell her how beautiful she is.
Also try to ask her why she hurts herself.

This sums it up. Also, don't hate her or shun her, help her, as best you can.

Support her and ask her if she wants to talk about it. If she says no, don't put pressure on her. The best of us self harm, and it doesn't make us any less human or have any less feelings. Ask her to phone you when she feels like harming, or ask if she can turn to her family for support. Encourage her to see a school councellor or psychologist about it. Shouting into pillows or holding ice-cubes tight are safer ways to relieve tension other than cutting or burning.
Be there for her when she needs someone to talk to :)
