Hope all goes in your favour, but be prepared for the worst.
Like spoon, when I was made redundant years ago I didnt have a clue what to do. It was the closure of the business so was not the only one. I just applied for every job I could and came out and told people that why I needed a job and was prepared to start at the bottom and work up if needed. Well I got a job as a delivery person. Now I am a store Manager and I really like my job.
Stay positive and if it is the worst case scenario, demand them to pay for things like a professional CV, etc.
I can imagine how you must be feeling today. Go play with your fish tanks to keep your mind off it for now as there is nothinhg you can do till you are sitting in the meeting with them.
Stay strong
