Hopefully, 4evrhisma is right that there is a chance that you need to give everyone more time to get to know you and see how you are working to act more comfortable around you. However, I highly suggest you brace yourself for a negative outcome as well.
I think if your current employers want to fire you they will. Your supervisor and the others will come up with valid reasons to do so that will be submitted in your evaluation. If that does not work, your supervisor and/or co-workers will make your working environment a living nightmare so that you will quit. If either becomes the case, I personally agree with those who say to move on.
I know that sounds wrong, but in all honesty it might be best. However, whatever you choose to do (stay or leave), I think you should document EVERYTHING!!!! Even document the actions of your co-workers. Who knows? If you have no choice but to leave because you were fired or because it is an unhealthy work enviroment, at least you have a paper trail to bust them for what they are doing and have done. Good luck.
