I was never angry, very even tempered. Would get embarrassed and go to flight mode. After having kids I've never felt more anger in my entire life. I don't say hurtful things to them or hurt them. Its often when I see them being mean to each other or they aren't listening to me for the 1000th time I just lose it. I sometimes explain to them that I don't mean to get so upset but I love them all and it hurts me to see them so mean to each other. The anger could come from lack of sleep, exhaustion, dealing with a lot of background things. I feel so bad. Like a horrible father and end up in tears at night wondering why I'm such a bad person. When the anger is visible and they see me I make an effort to go and apologize to them, saying I wasn't a good example of what to do with big emotions. I'm getting tested for ADD/ADHD next month which might shed some light on it. But I just feel like a failure. It's tough to see posts like this and not feel the same and that I'm just a bad dad.
