I lie about not self harming to my girlfriend
Why lie to her about something so serious?
I was scared of what she'd think of me.
I understand why you'd be scared about that, but hurting yourself is a very serious thing. You should come clean to your girlfriend about it, then maybe you can seek some professional help about it with her.
How can she help me? I really do not want to tell her.
I get where you're coming from but don't you think she at least deserves to know?
