Yes, it's a very tricky situation. While I'm sure there are some people that only deal with endometriosis, many of us have other chronic conditions that complicate the situation. I admit, it would have been difficult to hold down a full time job when I was in the worst of my endo pain. I would have one week of severe pain, two weeks of mild/moderate pain, and then one week without much pain. The week of severe pain, it would have been impossible for me to sit at a desk for 8-12 hours, which is what my work schedule was. So how do you hold a job when one week out of the month it's almost impossible to work? In the current state of affairs, many people have a work at home option, which makes it much more feasible to been gainfully employed. So, again, I don't feel like endometriosis, in and of itself, is grounds for disability. But like you mentioned, most people also have other chronic conditions which compound the issues with endometriosis. (I feel like I'm just rambling, so I'll stop here.)
As for how I'm doing, I've been better. I had a laparoscopy about 6 weeks ago that we were hoping would take care of some of the pain. Unfortunately, I'm pretty sure my pain has been worse since the procedure. I met with my doctor on Tuesday and we are planning on another surgery to remove my right ovary and possibly my appendix.
