Welcome to PC!
I am sorry you are having such a challenging time.
You had written about self-acceptance, which is something we all try to achieve.
It's tough to function if/when we are feeling inadequate for some reason.
I encourage you to continue therapy. If you do not find it helpful, you might seek out a different therapist?
I hope you can resolve your feelings of inadequacy sooner rather than later.
Be well and happy!
