I sweat too much

I could be sitting in a cool room and my armpits sweat. I walk to class & my armpits , my face and back are sweating... today I was sitting at the basketball court at 10 pm and my armpits are sweating .. also if I sit for a long time on chair my chair is wet & I pray every time that but but isn’t wet when I get up . It is so embarrassing. One time a guy told me there was a wet spot on pants😢.
