I’m so resistant to self-compassion it’s ruining my life

Self-compassion is something that’s come up in therapy a lot recently. I am now definitely convinced I have none of it, and I know when I need it, but when it comes time to do it, I refuse. No part of me accept that I’m deserving of self-compassion.

Affirmations and imagining “angels” hugging me doesn’t help. Does anyone have any actually helpful, practical tips for building self-compassion?

If it’s up to my brain, it’s never gonna happen and no one will convince me otherwise.
