I can't do this anymore!!!!!!!!!!

Being a single parent. I can't and really I don't want to. I have been a single parent for almost 11 years. I can't. He's a pre-teen and moody. I'm so done. All we do is fight. and all I do is yell. Since 10 this morning except for 3 hour I have been cleaning. Putting chrismtas crap away and cleaning up since I was sick this past week. All I get is my tummy hurts, i'm tired. can't we finish later. and if I say something like when we get home we will such and such and we don't I get yelled at. I'm done.
