Absolute exhaustion - how to cope?

Lately I’ve been dealing with one of the hallmarks of my PMDD, which is just complete full-body exhaustion. I’ve had some days off from work the past while and have wanted to make something of the days but just find that it’s difficult to even get out of bed, that’s how tired I am recently. 3 days out from my period and just completely drained

Does anyone else get this way? It feels almost pathological to be this tired all the time even while getting 10+ hours of sleep and while taking naps throughout the day as well. I want something else in my life besides this state of sheer exhaustion! It’s especially frustrating on days off when I want to do something fun and rewarding and just end up bedrotting. :(

About to go take a nap hahaha but I just wanted to see if anyone else can relate to this, or if I should be maybe considering other causes?
