I hate people.

Maybe it's time to go spiritual?

I've been through your situation (except that I had an awesome girlfriend who would listen to me) and sometimes I feel like The World is Not Enough (unintentional cliche). Sometimes I feel like no one cares and that there's a greater purpose for me in life.

I suppose my dad felt the same way and recently he's studied Buddhism and Feng Shui. Right now he's loving life again because of this new path he's taken. Financial struggles didn't matter anymore. Family pressures didn't matter anymore (my mum, bro and myself became the "second most happy thing" to him). Although it's pretty bad now that we're second my dad's really got that energy again and most of the time he isn't misanthropic.

As with me, my girlfriend and random searching on the net about different subjects/issues or topics (eg philosophy, current issues) are what help me keep interest in people and the world. Why are people like this? Why to they think this?

So three suggestions: Start relationship (if you want), read or try studying something spiritual.

Jam it back in, in the dark.
