Exhausted

I am 7 weeks today and completely exhausted. My son is in Kindergarten and keeps bringing home colds that turn into ear infections so now we have to see a specialist. My husband keeps getting the colds and whines more than my 5 year old. I have been lucky that I am getting them but they are very mild. I have been running around taking care of everyone else I haven't been drinking my water and I forgot to shower (who does that?) I finally lost it on my husband and told him to stop being a wimp and now he isn't talking to me and I don't even care. And he wonders why I fall asleep on the couch watching TV at 830. Just needed to vent.
