Do you have someone you can talk to honestly? Just one good friend can make a huge difference. You don't have nothing, you have people, and whether you know it or not, they probably care about you. You also have a ton of life, and a lot to experience. Think ahead to that thing you haven't done that you really want to do, not like a possession you want to have, but an experience or a thing you want to finish. That will take your mind off of what you have and don't have. I hope you're doing better, hugs!
