Its been a couple of weeks...
Moving home is not moving backwards. It's a lateral move that will give you a better job market to tap.
Moving home is not a metric of failure any more - I see more people moving back home to rely on relatives till they can get a leg up. That's become our new reality in this job market that seems to be stretching onto 5 years now.... Fortunately your parents live in a better job market.
And make sure you volunteer, and fill in your social calendar. You won't eat bad things, and your parents won't get on your last nerve.
I look forward to hearing about all your new adventures, old friends, and new job leads.
