Teachers, do you feel bad when you yell or speak harshly to your students?

I teach fourth grade Language Arts. I raise my voice, and if you notice, I have a question posted about hating my job and the discipline that comes with it. I often do not know how else to get their attention. However, I realize that all it leads to is them running over me. They realize this is all I do. I once heard a story about a speeding driver and a policeman. If the police just stood on the side of the road hollering for the driver to slow down, he wouldn't get much results. It takes them stopping them and giving them a citation to get them to realize they need to slow down. What I hate is going through with all the work of writing the citation when the speeders aren't going to slow down anyways. The good ones are going to be good, and the bad ones are going to be bad. I wish I knew some other way. I see other teachers control their cles, but I'm not sure how they do it. I feel bad sending them to the office or calling their parents over small things like talking or getting out of their seats at inappropriate times. There are many things you have to take into consideration. I have 28 in my cl. If you put any other normal person in there, they wouldn't be able to handle it. It is VERY stressful. That is why I'm considering quitting or changing something about my career. I'm not sure why people think that hollering at your students is a bad thing. I have children of my own. I hope they behave in a way that their teacher doesn't have to raise her voice to them. If she does, then, I think they deserve it. I know I holler at them some myself. I hope I'm not being too pessimistic. Consider this is coming from a teacher who isn't happy with her job. Good luck, and I wish you the best. Lord knows, I completely understand, and I do not judge if you have to raise your voice first thing tomorrow morning!
