Don't give up OP, just change it up. Stop sending the same resume over and over: try a new one, in a new format (or maybe even make a web portfolio).
But also, keep applying. It's all about balancing a mix of "continue the endless grind of applications" with "take bigger steps, like filling your portfolio with projects you start in your free time".
And of course also mix in some "go out in nature and otherwise take advantage of the time to improve your head space" ... because you won't get any jobs if your head isn't in a good place.
