Getting fed up with one of the puzzles, would like white flag option.

Is there a way to give up and just move on? I’ve been looking at this puzzle for a week, and I’m getting a little sick of it. I’d just like to try the next one, maybe put this one hold for awhile and come back to it. Either that or figure out where I could possible be going wrong with it.
