I get anxious anytime I'm behind the wheel. I get bad armpit sweats anytime I drive somewhere though I feel confident enough in my driving abilities and have never been in an accident. It's worse when I have someone else in the car. The same happens when I anticipate some exciting event and find myself having nervous/anxiety sweats around my own friends and family. In class, when I want to say something or contribute I can feel my heart beat so hard that my desk shakes slightly accompanied by sweating. When I do contribute, I do it through shaky words. 

I often wear tank tops for this reason which helps me feel more comfortable and not have to constantly worry about sweating. But, I don't like wearing tank tops all the time/in all social settings. 

I've tried medication once which I'm considering to give another shot. 

Any advice is greatly appreciated!
