I get so sick of this up and down bullshit. One day I feel pretty good the next, well pretty shitty. I hate being a hopeless romantic. I can't stand being alone, I love being with someone and now I have no one to be with. It makes it so hard sometimes. I know my ex is out partying her ass off and having the time of her life. I know I'm doing the right thing but sometimes it feels so wrong. I keep getting this feeling that I'm destined to be alone. I suck at meeting people, I'm way to shy, and it doesn't even seem like women are interested in a guy with a kid. I don't know anything anymore except I'm tired of having no one to talk to in person. At least I have friends on the internet. Well I'm tired of whining and feeling sorry for myself. It must be time for a beer. 
I sent you a too long email, sorry if it bores you to death!
I know what you mean about the ups and downs....that is SO hard to deal with. When is life going to go back to "normal", whatever that is. Hang in there, it can't stay like this forever.
