How to be happy?

I've just been feeling so empty. I've been this way as long as I can remember. Most of the time I don't feel anything. I've made some bad choices trying to feel something, and I'm sick of hurting the people that care about me just so I can feel. I need some ways to feel something. Anything. Watching horror movies worked for a little while. Gave me a nice rush. But it's lost it's effect. I can't get professional help and I have no one to confide in. I have no income and no car, so things like traveling or extreme sports aren't an option. Does anyone have ideas? I just want to feel something...
