Well, I know the feeling, a layoff can take a real toll on ones motivation. Almost like a loss of purpose, its a strange thing. You planned for exactly what has happened, but being forced to take the leap vs being ready to take the leap are two different things. Some more details might help to get better advise from people here.
When you say, close to FI? How close are we talking? Conservatively, how long can you sustain? What are your expenses? How much do you have saved? What passive income do you currently have? What liabilities do you have?
How does the wife feel about the situation?
One thing I would highly recommend, stick to a routine, still get out of bed at a decent hour, get dressed for the day, and get out the house and go do something everyday. In my experience, sitting around only makes the lack of motivation worse. Its also important to put things in perspective, if you are close to FI, then financially you are probably just fine. There are people way worse off than you right now, you are a rock star compared to most people. So think BIG, and plan for a big vacation or whatever you have dreamed of doing when FIRE, maybe set dates, work out trip details, etc.
