Hi Ipaidwithmylife
Arguments with family/loved ones are stressful in of themselves so it's no surprise you are feeling wound up.
Not knowing your history it's difficult to make suggestions but your psychologist does not, on the face of it, seem to be addressing your issues. Sometimes when I've seen medical professionals I have later thought "damp I didn't say ....." so now I tend to write down what I need to discuss rather than what my doctor wants to talk about
Sorry I can't be of more practical help
