A cut for every time my girlfriend doesn’t say I love you back
A million dollars for every time you don't.
Please don’t. It doesn’t accomplish anything. Talk to your gf and tell her how you feel. Talk to a therapist to help you overcome your urge to hurt yourself.
Make them paper cuts if you must inflict a cut each time.
Also, make them on yourself, not someone else.
Finally, ... grow the heck up. Get some mental help if you need it. Learn to deal with reality instead of denying it.
Honey.. please don’t do that to yourself... if your girlfriend makes you feel that way then she isn’t worth it. Break up with her, please don’t self harm
