You can't fault yourself for this...so don't be down on yourself. You did what you thought was best at the time and things changed. All we can do is make informed decisions based on the information we have at the time. You couldn't foresee this downturn.

If you look, you can probably find some places are still hiring...or maybe you just weather the bad times/possible furlough and get recalled? Do what you feel is right for you - but don't beat yourself up about it. Keep on keepin' on.
