Welcome to healing well. I am sorry that you have been diagnosed with crohn's, but please know that every case is different. Some cases are much more severe than others. The most important thing right now is to get a good GI doc - one that specializes in Crohn's. He or she can work with you on meds and diet.
I still drink my coffee every morning and I enjoy most foods. The key to this disease is figuring out your own body. What works for one person might not work for another.
Just take one thing at a time. If you are anything like me, you will find yourself amazed at your own strength. I also have anxiety with my crohn's so I understand your fears. I just take things day by day and TRY not to over think everything. I know, easier said than done
