OMGosh!!!! This is some heavy news hun!
What are the next steps?

Like so now you know what you got, now what to do to start the process of healing?
Are there operations involved?
Change of eating?  Diet
Did the doctor give you some idea(s)?

My aunt has Crohn's disease, did some research on it real quick:

Alternative medicine


Which do you have???

And I asked her - she said that you really really need to see a dietician.

Okay enough medical stuff out of the way.

Support...yes I know that while we may be able to be there with you and supporting you its not quite the same as having a human hand holding yours or a smile.
Actually human company is a Godsend - but heehee you could bridge that gap by getting hold of skype/yahoo etc and a webcam! Then you can chat for hrs face to face with any of us. Woot!
And about that ex bf... it depends on how you feel about it, but not contacting him cause you don't want to be a burden is not in my opinion the best of choices.
If he needs to handle abit more responsibility in his life then thats just the way the cookie crumbles.
You guys were extremely close and so I feel you should tell him, unless he really is not apart of your life at all.
He can be a friend.

Tell your family!!!
You might be taking all the responsibility for them and serious kudos to you at that - but there is a chance that you have been taking too much responsibility and they might have become 'lazy' cause they know you'll take the reins.
You need them now.
And I really believe that even after the initial shock horror there will be acceptance and a love will be automatically generated as the family pulls together and starts pulling strength together.
There can be much said for groups esp family units. You guys all chose to be together and there are many many reasons for that - who knows what they are but your higher selves seemed to think it was a good idea! heehee
I have always been amazed at how much my family can handle, I never ever thought it would be possible - I always thought...why not tell them?
You need as much support as you can get at the moment.

Even ask the Universe for support - maybe start a mantra saying something like "The world is conspiring to get me healthy" you never know what might pop out of the woodworks!

And like Mandimedea mentioned. We are certainly here for you in a big way.
Just holla!

Will also send good vibes and healing thoughts and some reiki

edit to add more info as I found it

Hi Mandimedea, I hope that your health has improved and that you feel more cheerful. Although your family may in many ways be dependent on you it is important to give them the opportunity to comfort and support you from time to time. When one is able to 'give' to some one else it adds dignity to one's life. Allow them to give to you in some way. Talk is cheap I know but I had my own struggles with health and dying and had to learn the humility that spoke to me being vulnerable and being able to accept help and support from those that I would normally consider weaker than myself and in need of my care. Once I understood this everything became a whole lot simpler.
It is also at these times when one is so ill and vulnerable that one is painfully aware of one's mortality. One must make peace with this. I struggled for a long time with the thought of leaving my children behind when I died and at some point it became clear to me that I had done the best I could for them including allowing them to care for me in my weaker moments and that I had to trust that what I taught them and shared with them would carry them through when I moved on. Funny how one's energy begin to be more available for healing when one stop trying to be Hercules and somehow it is often us women that believe that we must be Hercules.
Allow yourself...allow others...

At the age of twenty, you are surely burdened by seemingly overwhelming problems. Pancreatitis and Crohn's are never easy to deal with. Having them on a background of past appendicitis makes it worse.
Your family doesn't seem to be an answer to your problems, either.

But as the saying goes, "God helps those who help themselves" and I can see that you are a fighter! You are not just going to quietly fold up and sit awaiting your fate.
I think rather you will stand up and say, "Here I am, and I am going to look after myself, despite what you have done to me!"

And I wish you all the Luck, in this.
There are so many subtle Energies surrounding us all the time. Without our knowing, they sometimes become our 'family' or 'friend in our need' and step in, where we thought there is no one to help us!

Keep the Faith in yourself, and the bad tide will perhaps start flowing away.
