IMO, I think that MS effects our coping skills. Mine are not what they used to be and I notice a big difference. I often wonder if it has to do with the pain we experience, the fatigue, and some days just not feeling well. After a while, it gets to me and then my coping skills are much worse and my anxiety is much greater. It's part of a cycle, maybe even the pain cycle.
You have been dealing with quite a bit lately and that has a lot to do with it as well. Hang in there and take sometime for yourself. Keeping you in my prayers.
