More things rollin' around in my brain....

I hate the crossroads of life...... Ya know what I'm talking about when I say 'crossroads'. That point in life where you have really big decisions to make and you just aren't ready to make them. The choices that effect not only you, but everybody in the house.

I am going crazy in my own head right now and don't know how to stop it. I want to stay home and go to school full time. But I'm poor. Therefore, I need a job. I get a job and then school seems impossible. That is a minor problem.
The kids go nuts. That makes me nuts. They get cranky, then I get cranky. Jared is always cranky and Daddy just tries to hide most of the time. It seems like everything I touch falls apart. I'm hardly ever happy these days. I can't stop stressing over every little thing and every big thing. I just want to run away.
Then I feel guilty. Because I want to run away and hide. The house can't fit 5 people in it. Yes, 5 people in a 2 bedroom. Daddy has a room. The kids share a room and Jared and I get the living room floor on a twin size mattress. No alone time for us. No privacy, no nothing. I fight with the kids. I fight with Jared. I have nobody to talk too. And I can't figure out why it feels like I'm in the middle of the desert with no water. Too many choices to be made and no help. Every time I make a choice it hurts somebody. Why does it feel like I always do things alone?
I hear people talk about support systems all the time. But I kinda don't have one. I am the support system for some people, but for some reason it doesn't come back to me.... How can one person have so many people in there life and still be so completely alone?
