I'm sorry for shouting, I'm not normally like this.
We start off the sentence with the apology as it makes the sentence seem more sincere. By saying you are not normally like this, it implies that it is a one time thing and out of character for you. It lets the person know that you feel remorse or embarrassed about shouting.
I regret shouting at her, but she can be so difficult sometimes!
I hate shouting at her and it upsets me afterwards, but sometimes she drives me crazy when she ignores me!
If you want to apologise, substantiate your actions and also explain your feelings after this outburst, then it is necessary to form quite a long sentence:
"I hate shouting at her and it upsets me afterwards, but sometimes she drives me crazy when she ignores me!"
A shortened version may be enough in a public situation:
"I regret shouting at her, but she can be so difficult sometimes!"
叫んだ後に、謝罪し、行動を立証し、気持ちを説明したい場合は、かなり長い文章を作成する必要があります。
【例文】
"I hate shouting at her and it upsets me afterwards, but sometimes she drives me crazy when she ignores me!"（彼女には叫びたくないですし、後で私も悲しくなりますが、彼女に無視をされると時々おかしくなってしまいます）
公の場では、短いバージョンでも十分かもしれません。
"I regret shouting at her, but she can be so difficult sometimes!"（彼女に叫んだことは後悔していますが、時々とても対応しづらいことがあります）
I apologize for shouting at my child in public it's because she 'gets on my nerves' (annoys me a lot) sometimes.
I'm sorry everyone for shouting at my child in public, it's just that she irritates me so much sometimes and I 'can't help it'.
Children can be quite a nuisance sometimes. Often, they may do things that you may have told them not to do a number of times before, and, they will do that in public. You, as a parent, may 'lose your cool' (suddenly become extremely annoyed) and shout at the child because he/she is embarrassing you in public. The phrase 'I can't help it' means 'there is nothing I can do about it, I just have to shout at the child'.
So, you may say:
I apologize for shouting at my child in public it's because she gets on my nerves sometimes.
or
I'm sorry everyone for shouting at my child in public, it's just that she irritates me so much sometimes and I can't help it.
