Hay.

I know that I should walk away but I feel a tiny hope inside of me.

Should I give it a shot knowing that I have no chance? Would I still try knowing that it would not work out?

Since my life is greatly influenced by basketball....

"It is like a championship game. Two seconds left on the clock. My team is down by one. I have the ball and I am open for a jump shot. Should I take the shot or not? If I make it, we win and celebrate. If I do not make it, we lose and go home crying. So I might as well take that shot and in case I miss it, I will still cry but it would be less painful knowing that at least I tried."
