Hi Lucy -
I think seasonal change, environmental, another level of As, chronic fatigue all plays a part in how you feel. I left out the cymbalta, as I can't take any medication, and could not begin to tell you if it is not working anymore. Many days I get up, I am tired and as fatigued as I was the night before. My place is like a huricane passed through it.
I am looking into getting help (my boys - they say "mom your place is fine" - I think it's a man thing - they just can't see the dirt (men from KickAS are excluded - don't think I can handle - their retribution)). I can't handle my place the way it is. I think it's depressing me more every day.
This last week has been even more crazy - my car is in the shop and I can't get out.
No Lucy, your not nuts, it's the life of AS, in my case (PsA).
Hope your feeling better soon, and with lot less pain.
Hugs
Gerri
