WHAT IS THE PROBLEM THAT SO MANY PEOPLE EXPERIENCEThe issue I'm talking about in Sunday night insomnia. You just had a great weekend, and now it's Sunday night, and you can't sleep. And the more you can't sleep, the more you may get anxiety about the fact that you can't sleep. Bottom line - your social life, or just thinking that "it's the weekend - we can stay up later" thought process can be detrimental. It's when you can't shut your brain off, and then the fact that you can't sleep makes overthinking even worse.
