Adjusting expectations for myself, in general

I read somewhere the other day that many gay men have trouble loving themselves. Not like a narcissist, but in respecting themselves and in thinking that they are worth being loved. So I'm going to give this a shot.

Every day, sometimes many, many times during the day, I say that I'm stupid, that I'm worthless, that I'm a f*g, a queer, and lots of other bad things. I don't like that I do this, but I do it. Maybe it's because I expect myself to be something... different? Maybe I have it instilled somewhere deep down that I'm supposed to be straight, that I'm supposed to be absurdly smart and never make mistakes, that I'm supposed to always be approved of by others. I can sit here right now and know that these standards aren't realistic: some men are gay (including me); everyone makes mistakes, and making mistakes isn't a negative reflection on anyone; the only people who are always approved of by others are the ones who never truly be themselves. I want to change these expectations and standards that I hold myself to for whatever reason. I want to be something different, but I'm not entirely sure what that is.

On a side note, I really can't believe I'm going through this. It's like the past eight weeks or so have been a massive whirlwind of changes, in good ways. I'm finally processing stuff that's been bottled up for eons. I do wish, of course, that I'd had the chance to do this earlier...
