can't gain weight :(

Chloe • South Carolina 🌾
I've never been over like 107lbs in my life. I'm 5'2" and 19 years old I weight about 96lbs in the morning.. I lose and gain so easily but I can't gain enough it'll be like 2 lbs then I'll lose it bc I have Crohn's so I poop it out basically.. any advice on how to gain some weight. I can't have dairy or ice cream sooo?? :/
