Is there such thing as too much sweating???

So is there such thing as too much sweating??? I swear I have an
underarm sweating problem and I have no idea why. I can't wear cute tees
and have to wear hoodies so people don't see it and it smells bad when I
sweat. Plus I can not find a deodorant that works and when I told my
mom she just laughed. What should I do??
