Obstressing
When you're so obsessed that it actually starts to hurt you and you begin throwing insults at everything that moves.
I was so obsessed with my crush that I yelled at my cat for being cute. It was unfair.
I was so obsessed with my favorite food that I cursed my fridge. It was a silent war.
I was so obsessed with my video game that I yelled at my dog for barking. It was a sad day.
