That thing you’re working yourself through- others have done it too. No, not in exactly the same way. You are, after all, the only person who has ever experienced exactly what you have experienced. But they’ve been in a similar boat- tried to lose weight, wanted to exercise more. People who have been in more debt, felt as much pain, and thought it wasn’t possible.
This doesn’t mean your experience doesn’t matter. It means you can do it. It means you’re not the first person to experience this, and you won’t be the last. So keep going.
