School, work, baby ..... where's the sleep?

I have a new found compassion for working single moms, perhaps because I am one now but nonetheless, eeeks. I feel as though I have not slept in weeks and that is not the case. Emmanuel actually lets me get at least 8 hours of sleep a night, yeah I know!. Yet when I lay down to go to sleep my brain just wont let me. I lay there for 30 minutes ( 30 minutes of wasted sleeping time) and I just think. I worry about the bills, I worry about Emmanuel and his father, and then I think about work and then school and finally as I drift off to sleep Emmanuel's father finally calls me ( 2:00 am) and says sorry he did not get back to me earlier but he was working and what's up? WHATS UP? WHATS UP? ME !!! agggg. But I do not hang up because I still need to talk to him so 1-2 hours later as I'm finally off the phone and dozing back into a slumber I hear a cry from the co-sleeper next to me. SIGH!! Now where did I put that bottle? Out of bed, stub my toe, try not to scream, fill the bottle, feed the kid and lay back down. Now where was I. And then my brain all of a sudden turns on and I retrace my previous conversation with the daddy, did I turn in all my assignments, did I turn the burners off at work and lock the doors ?. And so on. I just want to turn my brain off and go to sleep. And yes I am typing this at 1 am because I could not sleep. I hope it gets better soon cause I am starting to look like a raccoon instead of a human.
