Relax, it's just a job. Family first. And sounds like you deserve the time together, your son will never forget them. You'll be back to work before you know it and be cursing.
When the dot.com bust finally caught up with the start up I was with in 2004, I got included in the 1st round of lay offs. Things felt dark, but in the end I rekindled my biking, dropped 30 lbs that I put on since joining that start up, and ended a bad relationship and met my current wife. In hind sight, it was for the best.
