Work on your resume and references, maybe take a class on it. Just be prepared for the worst, while hoping for the best. The more you do to prepare, the less helpless you'll feel.
Setup a LinkedIn, and get that fleshed out, get some connections on there and network. Keep it professional.
I used to check this site every day, looking for more information. I was one of the first to get walked out on Feb 12. Seeing so many people coming out after me with boxes of their stuff, it really hit me that I'm glad I wasn't there longer. I'm glad I got let go. I miss the people I worked with but I don't miss contributing to what UP is.
You are valuable, you have talent and skills, you will find something that makes you happy, a company that truly values you as an employee, where you're a truly valuable investment, not just a number.
It took me a couple months of searching and working through stuff but I've found my new home. You can and you will and you'll be much better off for it. Get out of there while you can, where you don't have to worry constantly if today's the day.
Start looking, take a class on interviewing and start practicing and getting that ball rolling. You will find somewhere that wants you and wants to keep you.
Put UP in your rearview and keep driving.
