would i be happier if i was stupid?

Im too smart for school, i dont study for anything and i have my head down in every class and i do the bare minimum and still pass. I feel like im smarter than the rest of them (just take my word for it, i prolly am). I never talk cuz i just know everything, theres weather, sports, drama (which i cant talk about cuz im the new kid), what do normal people happily talk about. Im so smart that im never happy and always lonely. Im also not considered ugly as a guy but im 5'6" and 125lbs at 17 years old in two days. When i get high, which i do, i feel like my organs might forget what to do, or my bones are just too out of shape. I feel everything i eat down to the molecules of matter it really is, like what i eat is the thing that im running on, the position i sit in ruins my natural blood flow. I have absolutely no interest in talking whatsoever. I take life as if it doesnt matter, cuz for instance, i sit at lunch all by myself on purpose just cuz after 30 minutes, it will never matter, no matter what anyone ever said today or yesterday, its all but forgotten after even 5 or 10 minutes. Im so intraspective because im the only person living in my body and everyone would prolly just cut me down or try to. I dont know what to do, i cant talk (unless someone here actually gives me great advice how to) and i dont seem to care much about anything, i wish i were dead often, and i get worried when im up at night thinking i might die if i dont use the bathroom (my hair starts falling out if i dont, it sucks). Ive never had a girlfriend even though i have proof of a dozen girls whom have had crushed on me, it also sucks.
