Personally, for me, I have found that I seem to have the worst flares when I am going through any kind of stress/trauma in my life. Age 12-13, puberty...Dx'd with CD. Age 18, lost both parents in car accident... bad flare, ended up in hospital for a week. 2 years ago I was in a motorcycle accident, my company shut down so I lost my job and was having relationship problems to the point we split. No health insurance so I just dealt with it and ended up in the hospital having 6 ft of my small intestine removed. I have had "minor flares" in between those times which required either little or no treatment, but the worst ones were when I was dealing with other stuff mentally, emotionally, or physically.
I have always felt the way you have. Maybe I expect it, so it happens...?
