Celey,
Have you been tested (however that is done!) for Fibromyalagia(sic)? Sounds sort of like those symptoms. But like a couple of other Crohnies noticed it sounds like depression along with fatique. Be careful with the excercise until you build up your strength, ok? I know it takes time. But God knows. I've done it 2 or 3 times in the past.
Take care & consider that advice about counseling, its good.
Sincerely,
Matthew
