Everyone makes errors. Once you realise you're part of the flawed human community, you'll feel better about your path.
Think of your anger when you make a mistake as a rite of passage. You'll fail, say the wrong things, and not get what you want. This is how life is, no tricks.
Don't let it get worse. You can control your mistakes, but you can't control your anger. Your life can be ruined by anger.
Don't use social media to vent. Your personal and professional life could end if you lose your temper or talk badly about yourself.
Walk, lift weights, or clean out your closet or garage. Useful physical exercise can help relieve this stress.
Tell a friend, family member, or professional, "I'm mad at myself," and explain why. They will listen to you and help you deal with anger.
Don't let mistakes make you say, "I'm not good enough." Stop going down the slippery slope of being a victim, even if you doubt it and believe your inner critic.
I wish for you to remember that mistakes are intended to teach you what not to do. "I'm mad at myself" should push you to do your best. Think about the lesson.
Your mood can be helped by working out, taking a break, relaxing, and doing other fun things.
Forgiving helps heal. You may have heard that this technique has helped people get better after being sick or going through other hard times.
