Have you considered getting a blood test to check your iron and ferritin levels?it could be related to iron deficiency.

I also deal with the extreme fatigue. If I have a full active weekend I'm often bed ridden for the next two days and still barely functioning until the weekend again. Sometimes just one active day is enough for pain and inflammation to ramp up in the days following. I wish I could say I've found a solution but I haven't. Other then resting when you need to after being busy and trying not to feel guilty about it. I guess it's also a shift in mindset, like I know that I can't clean my place and go grocery shopping or make dinner. I have to literally pick one thing sometimes, and that's often work and nothing else. Just know that you’re not alone, you are not being dramatic, this is a result of inflammation in your body and just try to be patient with yourself, because we are all pretty strong for dealing with endometriosis in the first place!

Me. I do have this underlying tiredness which was usually tolerable. But ever since my surgery, my tiredness has gone to a different level, I am constantly severely tired, exhausted. I don’t even know the word for it. There are days when I just lay in bed not being able to move. A simple things can make me feel so tired and it is so frustrating. I used to always be up and about, an early riser & can do multiple things at once. Now I feel like I aged more than 100years old
