I get very irritated when someone talks over me or interrupts.
When I really blow my stack is when I’m hyper focused on something important, and people who should know better, interrupt and bring everything to a screeching halt, and I’m the one who’s screeching screaming and yelling at the one who interrupted me.
I feel bad afterward, only when it’s someone I know, sorry but you should never bother a perfect stranger when they are obviously busy and not acknowledging your presence.
You are nowhere near alone in this area, I’m pretty sure this goes hand in hand with A.D.H.D.
