Don't worry be happy.

You're down, except it. No point going to the games living in hope. It'll be mathematically impossible sometime in March. But you already know the truth.
Go to the games relaxed and enjoy the rest of the season. You'll pick up the 2 points you need to avoid our unwanted record easy enough. And you never know you may mess someone else's season up for them if they take you for granted.
Put everything into the FA Cup you may spring a surprise on one of the big boys.
What's the worst that can happen? Getting relegated? To probably the most competitive league in the world?
That's not so bad
