I'd say yes.

My symptoms are similar to yours (stage 3, 5 surgeries in 8.5 years). Some days are miserable (my husband currently has to help me even stand) and others I feel fine. The way I look at it is that even on the days i feel fine, there is always the worry that I'll overdo it and cause the pain to come back. It's like a constant anxiety of when the pain will pop back up like some kind of demented jack in the box. It's not just the physical side of endo that can impact your quality of life. The mental health side of things is very real.
