Bad nerves

Hi, parents. Does anyone of you have problems with your nerves and calmness. I am asking this because looks like I have some. You know when I've known I will be a father it was like "Damn, it's awesome" and "Shit, no way" at the same time. I imagined how we will spend time together and it was awesome but currently all our life is not that I imagined at all. You know all these concernings about food, allergy, health, injuries, good sleeping and so on. This is looks like children comes to Earth to take away your time and your life to create their own lives. From the very day all these everyday things makes me sleepy and nervy. Looks like right now I am on the edge. Today we have a conversation with my wife which finished with her tears because I was a complete ass saying things like I am tired of both of them, I hate my son's screams, when he crying loudly and constantly requires attention. Each time my son whining (he is not talking yet), just mumbling or screaming even if it is a happy scream it makes me nuts. I am tired of the everyday life. Deep in my brain (heart?) I understand he is just a 1 y.o. boy and my wife like me requires attention and help because I'm at work full day. She tired too, may be even more then me. Does somebody have\had the same feelings problems? I know I am saying terrible things here but may be someone give me a good advice how to come back on the right track or may be it is time to eat pills and visit a doctor?
