How can I sell my timeshare?

I have really had enough with my timeshare company. When I signed up with my timeshare company they explained it would be an investment and worth a lot of money in the future. Here we are in 2021 and my timeshare seems more worthless. I have asked my resort if they will take it back but they wont, so I’m stuck with a now unwanted timeshare and paying for something I don’t want anymore. Is there anything I can do?
