Seems like you have an obsession with efficiency. Try doing some tasks in an inefficient way. Does doing things inefficiently cause negative self talk? Or does that make someone in your life mad at you? Remind yourself that kindness and grace matter more than efficiency. In an emergency efficiency is more important than kindness and grace but most days you need to let go of efficiency and just enjoy your life.

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.
