Yesterday my ex's current GF contacted me becuase allegedly he has a seizure after combining meds I gave him and she wants to start a fight.

First, I was not aware he had any of my medication and never gave him permission to take any of it. Second, apparently the seizure occured after she and him decided to combine a dozen different street/prescription drugs with alcohol. 

I am in a full blown "how dare you, I'll make you regret making me feel bad" and I can feel myself tipping into psychotic rage.

Anyone got any good coping skills to avoid falling into the revenge delusion?
