health issues, can anybody relate?

Hi, so this might sound like complaining but I just need to feel normal and find people who is going through the samething cause I don't know what to do. So, I have celiacs disease and lactose intolerance, I haven't been on my diet I'm supposed to be on sence I was born and I'm a chubby girl, I'm 225 pounds and I'm so scared to die from malnutrition such. My hairs in my small intestine are whiped out, I'm getting sicker and I'm sick of it all. But I don't have the money for the type of food I need to eat. And because I don't get the nutrition I need I feel like I'm always hungry. I need help finding a method for keeping to my diet and not eating what I shouldn't. So please help!
