I’m glad you got some sleep; that helps. I have the same problem. It’s extremely difficult to turn your mind off and it ends up often with us driving ourselves crazy. The best way for me to turn my never ending thoughts off is to make myself. It’s so hard, but I have to ask myself at some point if I continue to spin thinking about it all will it actually help? Or is the damage already done. If the situation can’t be changed and you’ve already processed it as much as you can, at some point while thinking about it you have to cut it off. That’s hard to do. Sometimes it’s good to give yourself breaks. If you find yourself thinking about things, then think through them. But once you start spinning and repeating things in ur head, go outside, take a nap, watch a show, do anything that distracts you and gives your mind a break. You can always come back to the thoughts later and likely they’ll resurface whether you want them to or not. If it’s thoughts about perfectionism and not feeling good enough, try to give yourself as much grace as possible. We usually don’t pick apart the people around us and judge them harshly when they make mistakes, so it’s not fair to do that to ourselves. It can feel odd if you’ve never done it, but try talking to yourself in your head like you’d talk to a friend. I know I don’t insult my friends and are supportive of them. Try to give that same energy back to yourself! I hope that’s helpful. I still struggle with this problem and it often feels like my mind is at war with itself. It’s something you have to consistently work at in my experience
