SAT: For beginners and for those who don't like Maths

I'm sick right now, please do not contact me. And do you wanna know why I'm sick? Because I have a weak gut! And I can't digest gluten and dairy so easily and feel bloated all day long. I am not having a condition, as long as I know. But I think I might have because I get sick so often. I really don't know. Maybe my intestine is just weak or maybe its because I'm a vegetarian? Maybe it could be because that's a punishment of my sins. I can eat spicy food though, it doesn't cause me too much pain at all, but if its indian food, I feel so bad and wrong. I can't eat oily and spicy food, it just kills me for 3 days. Now I'm pretty sure I would be sick for the next day too. It always lasts for 3 days, and 2 days have been through with pain. I might throw up. Only God can save me now.
