Am I treated differently.?

Okay well I'm a thirteen year old girl and my tutor is really awesome. We got off to a really bad start,she didn't like me and I HATED her. Then I got moved to the front row and we ended up talking about music when it was silent reading. And every now and again she tells me about gigs she has been to. And while everyone wasn't allowed to talk today she was talking to me about her favourite bands. I'm the only kid in the cl that likes the same music as her (punk/rock/indie) The other day I was crying about another teacher and she told me just to ignore them and to try and calm down and be brave. When I get detentions she used to be really annoyed now she just acts really sympathetic? She says she can't understand them because Im such a ''lovely'' girl. And In P.e we had her as a cover and she came and started talking to me. Now everyone in my year is been awful to me saying I get treated differently. I really don't see why ? And does she actually like me or is it because she knows I have depression and just wants to make me feel happy ? And to be honest....I think I'm starting to get a little crush, which is really bad so please help me get it away? THANKYOU!!
