*okay, please answr i am curious*?

Okay, I would just like to know what could be wrong with me, I sweat when it's cold. I mean I will be shivering and sweat will just pour off of me. I really dont sweat that bad when I am hot though, also it just seems to be at school!! just when I am cold, its really embaring because at school all of my teachers rooms are cold, so i sweat all the time, so i raise up my arms and there are big pit puddles. :/ I wear deodorant and i am just concerned that if i sweat constantlt that it will make it wear off and then i will stink and i dont want that to happen, can putting on too much derodorant make you aweat? cause i load my pits down with it cause i know i sweat alot. Please hel p me if you can. Thanks!! :)
