Feeling trapped and hopeless

What do I do when I feel completely hopeless about life? Like not that I think I can’t ever have what I hope for, but rather, that there is nothing in the world to hope for. There is nothing I can hope for or want. I can’t imagine any configuration of circumstances where I would be content with being alive. People want to call it depression or whatever. I think this is just where I’m at. This is just how it is. What can I really do though? I feel trapped in this situation, as if it is the entire world, far and wide and forever. I’ve read about what to do when you feel like this. People say “go outside” or “enjoy the little things in life” or “connect with friends and family” or whatever. I can’t see how that is a satisfying long term solution to anyone. It’s not like I don’t already do these things.
