Ever have those days?

I have been in such a funk lately and I just don't know why. Being a stay at home mom can be very challenging. About 4 years I passed up on a good job to become a stay at home mom. I thought it would really benefit my childrens lives, but I just feel like everyday is a struggle. The constant bickering, the constant battles of who hit who first, the constant battles of always feeling alone. I know I am not alone, there are people all around me, but I don't feel like I connect with anyone. I think this is because I moved so many times when I was growing up. I made friends with people and before I knew it it was time to move again and I lost that connection. Then it just became useless to me and I just don't try because it sucks getting close to people and then having it ripped away from you. I am jealous of the bonds that people have with their inner circle. I have always been the one looking in on those circles from the outside. I just want to be a better mom, a better wife, and just be happy. I don't think it's too much to ask for!
