Stress and Bullying behavior

God, it's embarrasing to even ask this, but does anyone else notice they get aggressive/passive aggressive when they are really stressed? I am very stressed right now and feeling like a jerk!
I'm behaving badly and just wanted to know if anyone has some coping skills?
Thanks.

My name is janette i have a 4 year old son with severe adhd he has been on focalin since 3. He to has those same anger issues when he gets stressed out. I notice its over some of the littlest things. i have tried to teach him about the "red zone" and when he reaches the red zone hehas to calm himself down. This is usually done by breathing and sitting with eyes closed. depending on his "disaster" this usuallly helps so try it
