So embarrassing!

I need help you all! Starting about 3 years ago (18 now) I started having bad underarm odor. When I would sweat the sweat stains smell awful and it's almost like I have to throw the shirts I sweat in out. I tried every method possible to get the stench out..vinegar...baking soda...air drying. Nothing is working! I would take a shower scrub my armpits dry off...add alcohol...deodorant (which I've switched like 3x now to find one that helps me smell good) and then put on a washed/dry clean shirt. The moment I start sweating the smell is back and it's so embarrassing. Sometimes in Church I'm too embarrassed to even lift my hands. It's beyond annoying and I've tried everything in the book to help. I also shave so there's barely hair. Aaaand another problem is I sweat BADLY! Sometimes it don't even be hot and my underarms are sweaty. When I'm anxious my armpits and forehead is soaked. I'm too old to be having hygiene issues- I can't seem to get rid of this odor issue! HEEEELLLLPPP!!
