Eating Disorder

Lying on the bed still and slanting my position is not a conformable way for me to blog. How I put this in an easy way.. It started when my brother invited guests over for an evening BBq party. It was a long pause in the beginning (going through all the preparation) but I can't stop eating once the food is finally done grilled on the hot stove, then it follows by as much dips as I can on the early prepared sauces. The guest also brought us chocolates and tip-bits for supper and I'm glad they came. The meal was satisfying, love the variety! The only regret I have is they miss out my favorite curry-marinated squid. t.t

Speaking of which, I do have this eating disorder habit. I don't have a proper time set on a meal, my meals always delay for no sort of reason. I eat whenever I feel I want to. But luckily, I have this amazing metabolism infuse with this tiny body I'm wearing. It's like I never gain any weight at all after secondary school. I was shocked when my 11 years old cousin was heavier than me, I was clueless before but now I'm positive that I'm clearly an underweight victim kaboomz.. a friend of mine does share this experience with me, she hardly gain a pound and she is so skinny that you can see the structure of her bone displaying beneath her pale skin. I only got my veins structure display on sight but still getting "do you eat" comment regularly. Some advice me on taking more fats but I hate oily stuff because they give me this nausea feeling after taking them. Furthermore, I only wish to gain weight but not fats. My brothers do not have this problem but only me, the only one in the family @@

So I want to know do you have this mutated metabolism like I do or you know anyone that has this ability? How do you deal with it? I tried eating but it never works on me :(
