Leaving the nest.

Okay, so. My brother and is girlfreind moved to Dallas to go to JobCorp. They told me all about it. it sounds so great. They pay you to go to school! I mean, that's awesome! Who doesnt want to get paid for going to school? It would be goos for me. High school just is not going well and it's to much bullshit. I'm fed up. So, I got to thinking about it and I want to join JobCorp. It's a great idea. Everthing's free. Everything. I don't have money and neither does my parents so I want to take up any oppurtunity that pats for every single thing.  What i'm geting at is I live with  my mom. My two brothers have moves out and my mom is divorced. So if I leave it seems my mom will be alone. That's sad and makes me feel bad. But I have to do what's best for me. ?right? It's going to break her heart. But she would be selfish to make me feel bad for wanting to do somthing with my life. I will always be close with my mom and I will come home every weekend. I can't help to think about what kind of daughter leaves her mom alone with nothing but three cats? but, she won't be alone. she has her parents and freinds. I really wish she could find a good man to marrie so I would'nt feel so bad about this. what do I do???????
