I get the anxiety thing. I would dread how I wasn’t going to sleep that night starting at about 3pm. That used to mean giving up in my way home and getting booze. Eventually I just had to try to stop worrying. Even if I tossed and turned or lied awake for 3 hours in bed, I would get something that resembled sleep and it was always better than waking up super hung over and even more tired during the day. It slowly fades. Even now when I sleep poorly, it’s 10x better than if I used.
