I think That I am depressed am I?

I'm 17 and i feel like noone cares about me or my feelings the main reason why i feel depressed because people always reject me especially girls they call me ugly and lame and they always hurt my feelings ive never had a girlfriend and when i tried to ask girls out they rejected me and when they did it was pretty harsh i feel like people judge me before they get to me all the the time no matter what i do im a nice person i treat everyone great but i get nothing in return some people say im too nice girls say im too nice to be with so they always told me no i love my life dont get me wrong but theres times like now when im completely down and i cant motivate myself at all i dont know how to handle this phase of my life help plz i appreciate it :) ?
