I'm sorry you are struggling with that. Anger & irritability are things I struggle with as well. Unfortunately I don't know as I have any particularly useful suggestions to offer. What I do is to simply try to be mindful of my emotional state & meet my feelings of anger with compassionate abiding. Sometimes it works... sometimes it doesn't. But I do think that, over time, the numbers of times it works have increased & the numbers of times it doesn't have decreased. It's an evolutionary process.
