Begin by taking a vacation - you deserve it, and it'll clear your head.
When I've sold my first startup I specifically wanted to get out on day 1 so I can go ahead and start another. This isn't for everyone - you have to decide how much entrepreneurial itch you have, and how much cash you have to back you up (you can move somewhere cheaper). The good news is that it will be easier to raise money next time round, so if you start anything, it sounds like you want to raise asap to be able to pay yourself a salary. If you feel like the risk is too great for you - get a job as a PM in a growing startup.
