Wakin Up In The Morning... and I'm Exhausted

So I know a user on here has detailed their experience about waking up at 3-4 am every day. And I experiencing the exact same thing but at 5am. I don't know, but I haven't had a full nights sleep in what feels like forever.

I'm not sure if it is because I work from home and I'm not getting enough exercise and so my body is like always "at rest". But I am TIRED YALL.
