Some people have an easier time than others. I am very easily irritable and I hate it. It's part of manic-depression. And if a Dr. thinks your problem is clinical there are drugs that are made to decrease irritability/agitation. If you find something that works it's like night and day and it frees your mind up to focus on other (better) things. My father can not comprehend my daily severe irritability, he has no problem at all with it.
