How to stay hopeful when you feel hopeless.

I have been feeling more and more like it would be better to just not to be around anymore. I could just rest and never have to worry about or feel anything again. The more I think about it the more peaceful it sounds, but a small part of me feels like I have to stick around. So some advice to help keep me grounded would be awesome. If you’re reading this thanks and hope you have a nice rest of your day.
