Im quickly spiriling into a monster

I don't even know what or who to talk to about this as I fear any psychologist will report me to the police.
Im not even sure if what I have is IED, but its something monstrous and it TERRIFIES me!

about 6 months ago I started to get randomly FURIOUS over any small inconvenience or perceived rudeness. Never outwardly outwards people, but out of site and in my car I would imagine myself beating on them so vividly my teeth would clench tightly.

The imagined acts keep getting worse to the point of murderous scenes in my mind and fantastic brutality. (like putting someone lower jaw in a vice till it shatters.)

Its like an energy builds up till I play out these things in my mind and I pull myself out to find my heart hammering and teeth biting hard and the energy gone for an hour or so.

my life is better than ever though! Ive cleared my debt, im making more money than ive ever had and far more than my bills. Ive moved into a new place and my job is low stress (except the driving. Road rage seems to be a trigger for these impulses.)

Do I have IED? where can I go to discuss these things because I found myself an hour ago around to suffocate my new 8 week old kitten because she just ran away from me and wouldn't cuddle.

I'm becoming something criminal and was not like this before!

Oh god, please someone point me to hope!

My most intense feelings of IED seem to get triggered by a couple of phobias I have, or by dealing with toxic people (those triggers can overlap too).

You say your life is better than ever, in a sense (apart from the IED of course.). Perhaps you have a fear of things not being so good again? Or maybe just being in this new "better than ever" situation triggers uncomfortable feelings.
