Very little patience anymore

Quick background. Roughly 4 years ago now,I went to court with my ex and received sole legal custody of my daughter who is now 7. So it's been just us since then. I also work rotating shifts. 5 days a week and sometimes a quick 4hrs on a Saturday. Needless to say I can get easily agitated, especially coming off of nights.And that leads me to this. It seems lately I have a shorter fuse then normal, with almost everything. At least I think so. Don't get me wrong my daughter is good. Doesn't really cause me any problems, does her chores, gets good grades and so on. But just the everyday things seem to really get under my skin.Example. Playing at the park. She is always the loudest kid there. Screaming. I was never raised this way. I'd get dragged by my ear all the way to the car if i did. It's like as if she doesn't know how to play.Even the way she sits at the table. I tell her to sit properly, I get a smart ass response. She always has an answer for everything.Like I said she's a good kid otherwise. But the frustration with just the everyday crap seems to really get at me. Which leads to raising my voice and basically being a dick. via /r/Parenting https://ift.tt/2MjQkgJ
