That would be terrible to have those feelings about yourself. I'm sorry. In my own way I have harsh self-judgements as well, feeling not good enough.

If you have mentioned these things to your partner, what do they think? Or else, do you think that would be okay to talk to them? Sometimes we need to take a leap of faith and trust (against our own beliefs) what other people/our partners tell us...even if it's just a little bit and not entirely. It's a start. Speaking generally, sometimes we can project our fears/insecurities and so we expect others to judge us in certain ways... because it seems logical and how could they not judge us in those ways? That's where trusting others can come in. Challenge our initial perception.

One core issue may be that there are things about yourself you've recognized you'd like to be different. If you think those things are truly healthy then there's some good to be found in those judgements, but most of all it's important to be kind to yourself. I'm typically not a fan of hearing to be kind to myself when people suggest it to me, but the more I learn of the world the more I believe there's so much good in us that we don't recognize.

You are clearly a thoughtful person. I would say in reality you are much better than you've described how you feel about yourself. But I understand if the thoughts feel so real and logical.

I'm not great at wording things, so I apologize if anything came across unfair that's my fault.
