I don't think you should. doing so can only result in a continued dislike in the game, or of playing games in general.
I don't know how many times I got sick of playing Star Ocean 2 so many years ago, until finally after like the 7th time of restarting it (after an urge came upon me to start again and again and again) I finally beat it by twinking out Claude near the end when it becomes a big grindfest.
