Do you mind if I lovingly challenge you on how your behaving?
Why are you making their problem your problem and enabling them to continue to be irresponsible? It's unhealthy. Also, "have to sell," is a lie. You're not a victim of their bad choices. You're making yourself a victim of their bad choices by not saying a kind, "No, I can't help you."
I would humbly encourage you to set a boundary with your parents.
