What a Weekend

So this weekend I made some life changing decisions.  I had an interview on Friday that went well and then I got a call this morning with an offer...EEEKKKK!  Now the ball is my court.  I had them email me the offer in writing so I could make sure it is really what I want.  I love my job now so I don't want to settle for a job.  I mean this is my career we are talking about...I want to be happy.  I am terrified now to tell my current job, to move, to find a place to live...holy smokes this is happening fast.  I applied thinking I wouldn't even get an interview.  Obviously my life is not in my hands, there is a bigger force working that knows whats best for me.
