My food allergies have actually [edit: positively] contributed to my quality of life greatly. Besides the fact that the only reaction is vomiting the food in my stomach (which has given me incredibly, incredibly strong esophagus control that's allowed me to binge drink for the past 2 years without ever throwing up, not even once, ever, I fucking swear), I've always had to think about my food choices and read my nutrition labels from a very young age when most kids would just devour whatever garbage their parents shat out in front of them. This made me aware of things most Americans have never even heard of such as "Calories" and "Servings per container" and "Fat" and "Carbohydrates" and "Protein" and the likes, and it's made me acutely aware of what types of foods are nutritious vs. what aren't. I'm a nutrition guru. Vegan for years (recently started eating fish, you can call me a Vegan+Fish... seriously look at fish, there's no way they exist for any reason besides to be consumed as part of an incredible diet). I'm more aesthetic (brah) and stronger than all my friends that swear by eating beef daily (rofl, idiots). I break necks at the gym, I have a big ass that's better than the asses of 92% of women. If my parents weren't idiots I could've easily been a professional athlete. On top of all this, it's taught me a bit of discipline. I can't eat cakes, some cookies, brownies, basically anything that's empty calories. The only negative is apparently walnuts are the healthiest fucking nut, which bothers the shit out of me. I try one from time to time to see if I'm still allergic. They're in a container here behind my laptop. Yep, still allergic.
tl,dr; this kid would be fucking blessed to be half Palestinian, and have my food allergies.
