Hello there dear friend. How are you doing? I hope that things are fine at your end. I believe everything has an explanation. A rational explanation to be exact. In your case I guess the explanation is very simple. Thing about it this way… When and why do you get angry? Start from yourself, it’s usually when things don’t go the way you want them to. Like for example at work or at the gym or wherever, doesn’t matter. You start screaming get mad and your behaviour changes a little right? Well no that much because you’re a grown up, you understand stuff. So you manage your anger and go on with your day. In your daughters case she is young. When she is at her mommies, the other children sometimes don’t listen to her… Mommy is busy and sometimes forgets about her. So this is probably just her being angry. This is just my opinion though. Nothing professional lays behind this. God bless you!
