As one who left Oracle this year after having enough quite frankly and no job lined up, I can tell you it's going to be OK. If you are a faith based person lean on it and your family. Don't fret. Put thing into action. Breathe and take that walk and even that cruise if you can and cleanse your mind and not worry. The world is bigger than any one company.
I thought to myself even if it meant a change in life, occupation, etc., none of it mattered. I am still in this thing called life. Life will always throw you curves. You have to decide whether to learn to hit them or take strikes. I wish you luck and enjoy the holidays with loved ones. It is going to be OK. I now make more money and I am appreciated. However, even if it meant me working at Home Depot or another outlet, I would make less and would have to adjust but still would enjoy life. Maybe on a lesser scale but live I would.
