When I have a flare, my symptoms are the same as yours, tflock. In the past three years, the only break I've had from those symptoms was for about four months. But I consider myself to be in a flare because I just haven't had a reprieve from abdominal pain, massive numbers of D, fevers, chills, loss of appetite, etc. for over a year. Alongside these symptoms, I also have joint pain, stomach distension, abdominal masses, and recurring fistulas, fissures and abscesses. While I consider myself as having a flare, I also name it as having moderate to severe Crohn's.
Like ShannonSankey, I would consider myself to be in remission or at least having a mild case of Crohn's if I were having more good days than bad ones. And where the 'bad days' come and go rather quickly.
