well said Lee, people are often quiet with newbees, they need time to get to know you just as you need time to get to know them, there will always be some who ignore you, you can't do anything about that, focus on those who don't.
until you are 'accepted' just think of the money it brings in and what that will allow you to do/buy. stick it out a while longer, you never know a really good friend may come from this job
good luck
take care x
