Really bad problem! 10 points!!!?

Ok ok, I have a bad sweating problem. Gross I know. That's why I'm trying to fix the problem. It seems as if every deodorant I try, it never works!!! I don't think it's a serious medical condition so I really don't want to go to a doctor. And it's just TOO embarring to tell my parents no matter how you put it. I can't afford any clinical strength deodorants. I'm sure you know that they run about $10.00!!! I've tried pretty much all of the Degree deodorants and the secret ones too. I need a very effective one that costs about $3 to $5. Or if there's any other things I can try!!! I'm open to just about anything :) And please, don't say EWE! or Nasty! That'll just waste my time...and yours too. So please, REAL answers only :P By the way I'm about 14 and a girl in case that has anything to do with it haha Thanks!!
