what do you do when it feels like it's too late for anything?

As much as I know that it's never too late regardless of your age I just feel like I have wasted so much time ad potential and being young feels like it was the only advantage and it's terrifying me because i have nothing that I want to start with let alone pursue a career, unfortunately I feel too burnt out and mentally/ physically defeated, all this waste of body and i can even barely make it by financial as all i have left is a dead end job.

It just feels suffocating because something has shifted and left me more scared than before. I fucking wish I could undo it off and it's eating me alive that I can't, even if I have a chance to start over I don't know how. I'm too weak and always restart myself when I've been neglected and defeated for the last decade
