Try and relax a little if you decide to go to the hospital if you8 can get somone else to drive you there,as would not recommend driving in your state.

If you go to the hospital they may prescribe you anti physcotic drugs to help control your temper and aggression,they have helped me as little things like people snoring on a train use to make me want to smash their heads in or just make my rage uncontrable.

If you not go to the hospital see your doc and make him listen to you,you might find just telling him and have him listening might ease the burdom.

Sounds like you had a panic or anxiety attack quite common and can be controlled with drugs.This made sound daft try and write down what your feeling in words or poems that will focus your mind a little or write on here,It use to help me write things on here when I was at my lowest ebb a few years ago.

There is no magic cure I give wish there was it will take time you will have lows but in time they will get slightly better.

Sometimes the best advice too take is what you would give someone else in your own situation.

You alone at work or is there people with you?

If you need to get something off your chest and dont wanna put it up on here drop me a pm mate I will listen and not judge
