I realized today how critical I am of myself.
Specifically how are you critical of yourself?
I relentlessly analyze my weaknesses.
It's good that you are able to recognize that you are too critical of yourself, but you still should take action to make changes. Realizing you're too critical is a good step, but now you need to actively try to be more forgiving of yourself. It will make you feel better and help you have better mental health.
I disagree, I don't want to forgive myself. I love being critical of myself. I'll continue this way.
If you continue this way, you will start suffering. Being too critical will not allow you to be happy.
