Hating the world

I don't feel loved and this makes me angry.

All borns an evening when I was talking with a woman about when I' drunk, get mad and have bad behaviors; and I was so sorry with who received this version of me.
She said the solution was less drinking, obviously; but now I'm thinking about it.
Except that i can't even talk with confidence if I don't drink "much", but I was thinking that probably I have bad behaviors not when I'm drunk; but when I'm angry.
And when I'm drunk I'm angry; i don't know if this is repressed anger, but it is so. I remember that I did or said bad things (maybe not with the the direct interested) and I don't know if this is so shamefull or gives me a position.
More I noticed how many people show their anger without problem, and many times others like them for this. But for me this means nothing, i just seem a repressed guy, and I feel i can explode even if i'm not drunk.

Like someone told me

You are apparently direct, you don’t mince words, and are not afraid to tell people what you think no matter who they are or how they might take it, or whether they should even care what you think (or may simply wonder why you seem to be so full of yourself). Your World view is self-centered, but in a self-destructive way.

But i don't know how to stop this. I started to be really kind and gentle, but seems like that people don't care much. Or better, girls don't care at all.
