What went wrong

It was so cool interview, I thought I answered every question Correctly ( that I always think anyways ) but I could see the interviewer agreeing to me .. You know what , he even asked me if you are ready to move to East coast ? I thought I was all set then ..
but after the interview , complete silence .. no response .. Ahh , I am waiting like anything for the reply . Every time a get a new email, I hope itz from them.. when I get a call I expect itz them .. god, I have become so crazy ...
and I know, when I expect things, it never works out that way .. All of my previous offers are from the interviews that I myself considered to be failed. So this time also I want to assume myself that I lost it ( hoping that I ll get it ) but this optimistic mood refuses to go away .. I hate it..
It is the company I always wanted to join ( though they earlier rejected me 2 yrs back, tht didn't have any effect of my love for that company ) .. they match all my criterias .. apart from that it was the last call among the three interview offers that I received .. and most important , I want to get hell out of my current job so desperately..
I need it .. ring the bell plz ..
