For as long as I can remember, my father has had a bad temper. Although the out-loud yelling name-calling sort of anger does show up on a rare occasion, it’s always been a more subtle, smoldering sort of anger. He’s always on the lookout for something to be angry about, and once he finds it, he isolates himself from the rest of the family and gives us the silent treatment. For example, last year he, my mother and I went to Florida and were walking around the hotel when her phone went off for a weather alert. He accused her of cheating on him and keeping secrets, then sat in the hotel room for the next couple days. I showed him what was on her phone and showed him all of her text history, but he refused to listen. “Don’t push me. I know what I saw.” I love my father, but there’s something about his anger issues that I know aren’t normal. There’s usually a span of 2 weeks to a month between the “episodes”, but reason I’m here is because today he was angry toward me and my mother without giving a reason at all, and I’m starting to sense a strain on their marriage. My father refuses to get any diagnosis or doctor visits, so I’m just wondering; is there a mental illness brewing here, and if so, what possibly could it be?
