Why do i feel like i'm going to throw up when i drink pool water?

every time I go for a swim, I like to drink the pool water cause its nice and cold and the chlorine is supposed to be good for you and stuff. i also like to stick my head into the pool filter and eat the bugs and stuff off the sides, they're nice and crunchy. my mom says its not good, and she tried to take me away from the pool, but I keep defying her and I just do it at other peoples houses. people dont invite me back afterwards and its killing my social life. why dont people accept me? anyway, whenever i drink the water it feel dizzy and i start dry heaving and stuff, but i try to keep the water down so i can reap the benefits of the chlorine. all i do is lay face down in the water and gulp down the delicious cold liquid
