Is there any way I can talk to a professional about depression online?

This might seem a bit melodramatic..Im seventeen, and lately Im a lot more depressed than I am happy. Every time I get this way, its like I have some kind of debilitating disease. I cant talk, I cant sleep, I cant eat, I cant concentrate on anything. I have not been diagnosed with depression, but I will not go to my parents about seeing a doctor who could. Even if I could go to my parents, I wouldnt want to. People will think Im crazy. My parents will think Im crazy. I live in a small town where they are not accepting of this kind of thing. I just want to talk to someone, preferably a professional, over the internet where I dont have to see their face or know who they are, and they dont have to see my face or know who I am. I just want a second opinon, to see how I should continue.
