A bad sweating problem!?

Ive been having a really bad sweating problem. Ive tried probably all of the deoderants. It started when i started shaving under my armpits. I cant wear hollister or aero shirts because it shows and when i do (summer) i wear a jacket so you cant see it. I even shiws on tanks and tshirts too!!! My mom just says its puberty and gets mad because i dont wear certain shirts but she doesnt understand! Its soooo hard and i cant take it!!!! Can someone please help??
