I'm just so tired

amy
I've got a beautiful baby boy who's going to be 3 months old on Wednesday, and I've been doing the nights by myself and every day since his birth I've looked after him entirely by myself, and it's all started to get to me. I'm a single mummy, first time.
I just feel so crap!! I'm so tired, I can't remember when I last showered, or brushed my teeth because I simply do not have time. Sometimes I go out with the pram purposely to send him to sleep but then when I'm out I get so angry that he's asleep in public because I can't nap in public!! 
I don't really have any mommy friends, I'm too shy and tired and busy to go to any clubs or groups, I just am too tired, feel like such a failure 
I just needed to vent to somebody and I know all the mummies on here won't be judgemental... OH!!! And to top it all off I think he's started teething!!!
