If you want to leave, it’s up to you. We on the forum can’t make that decision for you, nor do we know how much of an effort you’ve put in. If you truly think there’s no room for improvement, and that you’re gone as far as you can, so be it.
If you decide to stay, then how much time and effort are you willing to put into improvement? Have you exhausted all your resources? The category “Tips for Sellers” is quite big.
