guilt for blowing up

I have three kids and the amount of guilt I go through for showing my anger is immense. I mean you can understand how many times one would lose one's temper.It was difficult with my first born because for her it was the first thing to deal with it and for me as well. But for the other two, they grew up seeing it a regular thing or I would say something that happened with the first one or with both the elder ones. I think there is no other way then acceptance. I always accept losing my temper to be a bad thing and apologise to my kids. This has worked too. I tell them that I too am a human being and like sometimes they get irritated and angry with me or things, same way I also get angry, and of course which is not a right thing, and I am working upon it. And I seek their help to control my anger. Conversation not only helps overcome my guilt but it has also helped me actually keep a tab on my temper.
