My specific situation:

I started dating this guy. We were together for about a month. Everything was great up until this past weekend. He made me laugh,  made him laugh, we had fun. The whole time though, I didn't feel a natural connection with him, and I KNEW we weren't right for each other. I kept trying to force myself to really like him. I suppose it was mostly physical attraction that made me want him so much.

Long story short, after a few really lame occurrences this weekend, I realized that this was the start of an unhealthy relationship. I knew what I had to do. So last night, I broke it off.

Now I'm really depressed. I miss him. I want to be with him. I want to at like we used to. Laugh and goof off together. I want to kiss him and cuddle with him. It hurts a lot. I get really attached really fast and have hard time letting go.

I KNEW, in my gut, that it was the right thing to do, but it hruts so much now, and I want it back, even though I KNOW we shouldn't be together.

I just don't know what to do with myself right now. I've been painting to try to distract myself, but, it's not working.
