I’m certain you have blind spots, too.
You can ask people you’re close to about them. You can dig them up on your own. You might dig them faster with a therapist. It’s completely up to you.
It’s possible you aren’t aware of how you come off to others at times. That’s human. I believe that to commit to doing better, is within you.
One way to become aware of your own blind spots is very simple--and may be hard to take! When you find yourself going off on someone, using “You” statements (e.g., “You never pay attention to what I say”, or “You _____, _____, and ______”), hold a hand mirror up in front of your face, and say it exactly the same: to yourself.
This won’t be fun. Be kind to yourself, and wonder what you can learn.
