I get it: some people leave Vegas married to someone they had never previously met.
You are now in a committed monogamous relationship with this RAV4, so focus on what you like about it.
Your credit score sounds like it needs some attention. It may be something small/simple, or a crime scene. Make sure you check all three bureaus for errors and their respective FICO scores before you try and lease again.
Cancel any warranties / add-ons you can,
be grateful you leased something that is so reliable it will bore you to death, see if switching gas helps. But drive that thing until you clean up your bureaus and educate yourself on a good deal, because you got railed (which - as a potential customer of yours, I’d be more horrified at this deal than what you are driving). But anything you do will cost to transact, just minimize that for now.
