Is it possible to repair your reputation?

Quite awkward but I do know how to mask sometimes with new faces . This is mostly work related. I can get by enough for the interview but after day 2 everyone hates me …not that I care , but it would be nice to just feel normal. It's such a odd dynamic how everyone can easily dislike me and haven't even said much to me . It may not be as bad as I'm describing…but just so awkward. Thank goodness my new job is more independent so I don't have to deal. With much people . Starting off I do speak to people I haven't yet not introducing myself but a simple " hey how are you doing ? " not to force it but since I will be dealing with them why not greet . They form a opinion after that fine , atleast I made the first move if your not fond of me after that it says more about you …but for the ones I haven't got too yet it's the animosity if that's the proper term , and passive aggression before anything which turns me off to even dealing with it . I do respect myself so I ofc am not too worried but since it's something I will be frequenting often considering it's my workplace just how should I move on from the oddness ..if you will and rebuild a more positive image ?
