My sweating is absolutely out of control help?

I'm 21 years old and female. When I was younger I always had like a "shiny" face from it either being oily or sweaty, but thought it would subside as I got older and went through puberty and all that. But now it's horribly, horribly worse than it was. Whenever I bring up or encounter the slightest stressful situation my armpits literally "cry" and it runs down my arm and onto my hands and it's the most embarassing thing, especially being a girl. When I'm hot I sweat, when I'm just getting out of the shower I sweat, after I put on anti-perspirant I sweat, even when I'm normal temperature or cold I sweat. I've seen my doctor about it and besides treating my anxiety and depression, he says there's nothing that can be done unless I pay for botox injections but I'm scared I might have some disease or deficiency of some kind. Anyone experience this type of thing? What can I do?
