Everyone at work hates me?

I just started a new job about a couple weeks ago. I'm in college so I feel I'm lucky to have a job again (didn't for a semester & depleted my savings.) I'm a very nice person, I don't say anything bad about anyone and I'm very kind to absolutely everyone that I meet. But, for some reason at this new job, everyone hates me. They're constantly talking about me and sometimes I overhear them if I walk into the room, or catch their whispers as I walk by. It's so awful that I dread going into work and it's affecting my outlook with other people. I'm starting to think that everyone there hates me. The majority of them are outright rude to me most of the time, or don't say anything at all (even when I try talking). It makes me want to cry but I don't, usually go to the bathroom if something happens 'til I calm down. I don't know what to do. I've had jobs in the past and been the new girl before, but never in a situation like this. I feel like everyone's out to get me! Please tell me what to do. I can't just quit the job or tattle to my manager, that would make me look bad. If anyone has advice, I'm open to anything! Thanks in advance.
