Sadly I have had a lot of experience with unemployment. Get into a routine that forces you to get up every morning. If you need to make phone calls you want to catch people before their day gets out of hand. Work your (human) network--of the seven jobs I've had since the eighties, six of them I got through referrals. (The seventh was because I'd put my resume out on all the job sites and a headhunter found me.)
And take advantage of your "vacation", but productively. Work out, fix up the house, take a class. You won't have time for any of that once you're starting a new job.
And good luck. Remember: you are not your job, you're not how much money you have in the bank, you're not the car you drive, you're not the contents of your wallet, you are not your khakis.
