Dealing with cancer while dealing with my own

There are so many stories, so many journeys and many of then so much harder than mine. I just keep putting one foot in front of the other telling myself I am fine. But it is the really little things that I find hard to deal with. I finally put 2 infections after surgery behind me and was given the okay for some intimacy. But before I got there I now have painful tears. Just as I think a bit of normal returns I am proven to be wrong. Again. I am so frustrated about getting emotional because let's face it, these are such minor issues but they really knock me down.
