Ebb is a good term. Any ebb tide is followed by a flood tide. In the meantime, what an awful day you had with the E.R. and the vaccine side effects and the inevitable but unpredictable return of grief. I'm not sure this addresses your basic reluctance to ask people to drive you to the E.R., but when I was having to go there regularly, I'd try to get people to just go home for the waiting time. But with luck, you won't have to worry about it again for a long time.
