I agree with UK and BMo3. Very few go through life without any hardships whatsoever. Crohns is a tough one, but to live with. Still, your emotions are going to yo-yo over this, especially so early with the diagnosis while you're still working out how to manage it. Think of this like breathing -- out with the bad air, in with the good. Don't deny your emotions. Allow yourself to wallow when you need to. Let yourself have a good cry. Then when you sense you're bouncing back, draw those good feelings in deep. Congratulate yourself on finding that recipe for -- oh, say banana marengs -- that tasted so delicious and slipped through your guts with no pain. Be proud of how you managed to find a toilet in the nick of time. Be super proud of how much you're biking and working out!!! In other words, give the positive feelings all the boost you can when you sense them easing back in. But don't waste energy denying the bad ones when they're there; better to find a good warm blanky and a weepy movie and let them out.

Hugs and ... well, the butterflies are all hibernating here now, but I have pictures to remember them by.
Duck with Crohns.
