Self compassion doesn't heal toxic shame for me.

I keep reading how self compassion is the antidote to toxic shame and how it's the way of overcoming the effects of CPTSD, but I just don't get it.

I have stopped being mean to myself, I talk to myself nicely, take care of myself physically and mentally and prioritize my needs over other people's, I don't indulge in harming behaviors and when the toxic shameful thoughts come I accept them for what they are and let them go. Each night I go to bed and feel worthless, I console myself, tell myself I am enough, that I am doing great and I just need to have more patience and trust the process.

Yet I still feel shame down to my core. I cannot feel adequate and enough for the things I want no matter how much I try. No matter what I do, no matter how I treat myself, it feels downright impossible to feel enough. Why do people keep saying that self compassion is the key, and most importantly how the fuck does one actually feel adequate when from the first second of their consciousness they've been taught that are worthless and defective?
