I've found what helps me feel better is feeling like I have some control. So that can mean doing one thing a day that is in my control (eg a yoga routine, or cooking) when I can even if the rest of the day I'm in bed, or making an active decision to take time off rather than feeling forced into it by the endo and then stressing about my work.

Brain fog, becoming more introverted than before. And having to cut out people who did not believe I had endometriosis or gave me a hard time for it.

Depression

I would always doubt myself because I knew how Endo affected me during flare ups and I would also be irritable, and forgetful and anxious when my hormones were all over the place. It was just mentally draining.

Brain fog. Low mood. Especially when the pain is bad.
