Good luck. If you prove yourself to be helpful and a hard worker, perhaps they'll come around. Try not to take it personally.
Don't have expectations on how they "should" behave and perhaps you'll have an easier time. I took a similar job the last six months of nursing school and they didn't roll out the red carpet for me. Didn't they know who I was and that I was the most important person there?
If things go bad you can always post a "Why Do Nurses Eat Their Young" thread.
Seriously, make the most of your experience. In time as they get to know you'll I'm sure it will be fine.
