I get really nervous every time when I'm about to talk to someone. My heart starts beating really fast and I get really nervous. When I get nervous I sweat a lot. After I calm down I'm comfortable. Sometimes I get nervous for no particular reason. Can someone help me?
Sweating because of nervousness is normal. Becoming nervous at new situations or in face of something that you don't the outcome is fairly typical. The only thing that concerns me is feeling nervous without a particular reason. There are a few medical problems that have that as a symptom, so I would like you to see a doctor tell him about this last problem and see if he can pinpoint a cause.
Otherwise, it is experience that will help you become calmer. As you realize that you can deal with each situation, you won't become as nervous.
