2 hours of grinding in one hand, can I fold?

Hi, so I was playing poker for a few hours and managed to grind up a good 250 dollar stack at 0.25/0.5. I’m playing with a bunch of guys that don’t seem to take poker too seriously, and what I’m wondering is can I fold here? It kind of hurts to lose 2 hours of work in this one hand. My friends tell me AK is a drawing hand so can I just call off a pair? Seems too much to invest 250 without seeing the flop. Wondering what others would do here?
