Sorry it is tough for you right now. My inner critic gets the better of me sometimes. When I can motivate myself, going out for a walk helps, as does listening to music. But mostly, I just remind myself, that when it's had it's say, it will become quieter again.

You're not a failure, it's just that the voice can get too loud sometimes.

I know it can be hard, when you're feeling small and vulnerable too. I guess at such times, that critical voice sees it's chance to have a rant.

Hoping it takes a hike soon and gives you a break.

Take care, you don't deserve to be hearing that stuff.
