For those who might see shame in filing for unemployment - are you aware that this is NOT a handout, and that this is a benefit that you have earned by your hard work?
This probably had nothing to do with you and was a business decision that you are not supposed to take personally (though you probably did). Hopefully, you did not cry in the office - but feel free to do it now. A lot of our identity, good or bad, tends to get caught up in what we do on a daily basis or where we are in our careers. There are potentially a lot of emotions going on inside you, and they may change rapidly. It's OK. Don't get upset with yourself too badly if you aren't in the greatest of moods or feel like retreating. It's awful and not at all fun to go through this stuff. Luckily, time moves on and this too shall pass. If you can try and adopt the "door shuts another great one opens" philosophy, it may make that time even shorter.
