Hi guys,
lately my mind has been waderring into mistakes i made in past. Like embarrasing stuff or stupid things i did when i was young and reckless. It keeps playing back in my head and i cant shake those thoughts off. Those things dont matter anymore and i have learnt from them, but it still bothers me and disturb my thinking.
I dont know what started this, and there are no consequences or anything. For example i keep thinking about stupid thing i said like 6 years ago, and i still beat myself up on it.
Is there any ritual or something i could do to let go of that? Should i write it down on a paper and burn it or something?

Thanks
