Good enough to shake my temper

When they are still around 1 year old to 2 years old maybe we still can hold our temper or anger or stress when deal with kids. As i am mother of 3 and full time working mom(8.00am-5.30pm) , i do try my best struggling balance my kids,career,husband, and house(keep it clean,tidy and comfortable). But sometimes i do feel so down as i am exhausted from work whereby i have to continue all the house work such as cooking,laundry, and other chores. This is the time when the kids throw their tantrum, cry no reason continuously yet i asking softly "what she want/what happening/"..until it reach to the limit which i can not barely hold my temper and burst it out with screaming,, surprisingly they do stop all the nonsense annoying cranky. But after that i have to admit that i feel guilty for being so rough and loud to the kids. This is always happen to Ruran and Rinai.

Still do my searching on how to deal with this madness before other serious thing happen like "whack them or anything else. I know that they are innocence little kids who are need our attention. But the way they ask for attention make us annoying. They are kid and that is how they want to express their needed to parent/adult(us).
