The bitter sound of jealousy and self pity.

So not too long ago I dumped someone. I thought it was the right thing to do. But now I find myself upset. Why? Well:
1. I'm packing and that always makes people upset.
2. My "best friend" likes the guy I dumped.
3. I think I still like him and I know he still likes me.
4. I'm with someone else and I feel guilty.
And dang.. yeah.. I'm mad. at her. at him. at me.
