My inner monologue is almost crippling. I can't fall asleep at night, I think of all the stupid shit I've done and said in the past, and I call myself names because of it. It's gotten to the point where sometimes when I'm alone I'll vocalise these names I call msyelf out loud. It sort of helps to relieve the stress of reliving cringey memories... But I'm not sure anymore.
It sounds harsh but the best advice I've ever received is that "people don't care about you". The context in which it was said was that people engage with you when you're there but when you're not you can expect them to be caught up in their own life, problems, issues and listening to their own inner voice.
