It sounds like you are doing all the right things for yourself. Getting out of a relationship always hurts, regardless of who broke it off. It shows great strength that you were able to make the decision and follow-through with your choice.
I understand the changes that Crohn's has brought to your life because my world was flipped upside down by UC. These diseases can take a toll on us both physically and emotionally.
Have you ever heard of CBT (cognitive behavioral therapy)? I can't say it is your "fix" but it does teach a person how change their "stinkin' thinkin'". There are resources available on the web about CBT, and you could also ask you counselor if they are knowledgable on the subject. I've used it successfully in the past to help me get out ruts.
I hope you are able to start feeling better soon. Are you stable on your Crohn's meds, or are you still in a flare? It is hard to see the light at the end of a tunnel when you are flaring, but it helps to identify the little bright spots you have, and be thankful for them. Try to take it one day at a time.
