Good for you for seeking help. Try to ignore the comments that are pure judgement and no advice.

You need to ask yourself - why you get so mad over mistakes? Maybe you were brought up in an environment that wasn’t safe to make mistakes in? If so, you’re now making your house an environment that isn’t safe to make mistakes in. You have to talk to yourself. Tell yourself you want to break the pattern. Tell yourself everyone makes mistakes. Tell yourself you should have been allowed to make mistakes in the past. Tell the person you lost your temper with that you’re sorry and all the things I listed above.
