Hello person!

This is currently my first ever question. I thought that this might be a good way to vent my emotions out over the internet because I'm feeling a bit down lately. I think there may be something really wrong with me in the head. I do not feel any emotions but I know what I should be feeling. I look at my girlfriend and I honestly don't love them (it sounds a bit weird, and this also applies to "friends" and family). It's gotten to the very point where I am actually harming myself just to feel something again instead of this hollow emptiness that I usually feel. I don't really have any friends at school and I feel nervous to talk to people in real life about my problems hence why I am on here.

I was just wondering if anybody else out there feels the same as me, like an empty abyss of a black hole sucking me down, draining me. I am losing the will to go on with my everyday life not feeling anything, I really just want to be normal and happy like everyone else. Why do I feel like this all the time? The things that used to interest me like sport (football and cricket) no longer interest me and I have quit. All I do with my life is sit and sulk in my room wishing I had a better life, jealous of others around me.
