Hurting yourself

So I’ve hurt myself before just once and now as of Friday I️ made a promise to myself and my girlfriend that I️ would never hurt myself. This post isn’t about how I’m feeling all depressed and want to hurt myself so you might be wondering why I’m talking about this. Basically I️ was just thinking and when I️ hurt myself I️ kinda don’t really know why. If you’ve ever hurt yourself or anything just why. Like I️ know you’re deplorable whatever but what makes people, myself included, want to feel pain or whatever because of they feel depressed.
