When you know you're doing it wrong

Doesn't it eat you up to know you're screwing up... Living with high aspirations, probably impossible ideals. Knowing it's not sustainable, that you're hurting yourself, that you'll isolate yourself, that you'll drawn in your own shit. Knowing that you'll kill yourself if you keep living that way. After you realize, what is there to do... What is there actually to do after you realize.
