A little advice
I was diagnosed 2 years ago. I'm 20 going on 21 years old and I have to say that thankfully I have been able to control my Chron's quite well! In the begging all I want to do was be in bed and I would get easily angry at everyone and everything. I was the most easy going person before and it was extremely hard to get me even a little angry. So I shut myself away from everyone and just started to try different foods little by little, to see what would help me out the most. I also read that working out helps so I signed up at the gym and I also start taking Yoga and Pilate's, which in turn gave me a calm that helped me get rid of daily stress. Now my diet consist of carbs and protein, like: Turkey, Red meat twice a week, Tuna, Salmon, Chicken, White bread made with no milk, and rice. If you make ur own mashed potato's then you can get that too, even streamed vegs but only very few times a week. Fruits I have a smoothie I make at home 1 a week. As for sweets Lollipops are great!
If I ever get thirsty I make tea of all sorts but always made sure they don't have any lactose!
I hope this becomes helpful for others and I wish others the best of luck :-)
