Serious perspiration/deoderant problem?

Ok. I'm about to go crazy. I have this problem within the past month or so. Whenever I wear deodorant, my arm pits are really wet and it leaves big wet stains in my shirts. But the stains smell like pure deodorant, so i know it's not sweat. So I thought maybe if I just don't wear deodorant until I need it that will work, but it doesn't. Because then I sweat for real and when I put it on, same thing happens. I constantly have to be shirtless until my arm pits dry but If I put a shirt back on or anything the same thing will happen again. It's really driving me crazy. I've tried using about 5 different deoderants, two saying antiperspirant on the cover. I'm a 19 year old guy, 5'11 and 150 lbs. I also thought that maybe it was a hair problem so I trimmed my hair thinking it kept too much moisture but that has not helped at all either. It's gotten to where its all i'm thinking about , thinking about how nothing works, how uncomfortable it is, and i can't take it.
