crohn's itself wont shorten your lifespan it just makes life harder. you have to know where the bathrooms are and you will have to modify your diet. the only thing is there is no specific diet to follow. keeping a food diary helps becasue you can see what foods work for you. sometimes i can tolerate some foods though and other times i cant so its a crapshoot. but you will get thru it. i know how scared you are. when i was first dx'ed i was really scared too. sometimes you may need to go to the hospital and you will probably be on meds to contril it for the rest of your life. but it will become routine for you. i promise. the only thing i can offer is that it does get better. the meds can bring you into remission, i had a good long time where i had no symptoms at all when i was on remicade. at some point they may need to change your meds, sometimes that heppens too. but try not to be too scared. you will be able to live your life, do what you want to do, just maybe a little differently.
it will be ok. coming to healingwell is a great decision. there are so many knowledgable people here and so many that offer you the support you need. and you can tlak about anything! poop, pain, or even just to rant , get advice or just to talk. welcome, im sorry you have to be here but welcome to the community.
i hope this helps
