Kindof Awake

Im pretty sure when i gave birth 6 months ago all my energy went out of my soul and into my sons...he refuses to nap and only sleep for an hour or two at a time at night, yet he is always smiling. Me on the other hand....ummm not so much I am so so so very tired. I am pretty sure i have some kind of deficiency. I get plenty of rest, I hardly ever do any activity besides clean my house and I feel like I have been ran over by a truck. Anyways I am trying my best at the moment to get my rear off this couch and go hang up my sons clothes but chances are slim and if i do start i will stop in the middle and get right back here in my comfy spot on the couch. WOW what have i become....a big fat loser, or perhaps a stay at home mom of a 6 month old whos dads in the middle east and she has no one to lend hand...im not sure which one I am at the moment but I know I should call my doc about all this sleepiness...anybody have any suggestions on what might be my problem??
