Do I have hyperhidrosis?

I seem to always sweat through my shirts, only in my underarms, and normally when I'm around people, or outside of the house. I've only tried normal of the shelf anti-ps, (Lynx Dry) I've just turned 16, and I'm not in the best of shape (I'm changing that though). I'm not to keen on going to the doctors either. Do you think its just a hormonal thing? Or hyperhidrosis, Nobody in my family have it, seeing as its mean't to be genetic? Thanks for the help :)
