I can't go on
Why do you think you can't go on?
Because I'm done talking to you
You can't help how you feel. You should seek professional help if you feel you can't go on.
I just want to scream and break shit. Maybe it helps me
People get angry all the time, but it is necessary to control your anger so that you don't do things you may regret later in your life. If you break stuff you would end up spending a lot of money to replace them and you will hurt people you will scream at, so it is better to be calmer and be more polite than being angry all the time.
