He would never ask for help to begin with, but assuming a literal miracle occurred and he did, the next question you’d want to ask is “Would he accept the kind of help he needs?” He just wouldn’t, it would require work and a level of willpower he’s not capable of understanding. He would have to suffer responsibility in the present to provide him some freedom for the future and he just can’t do that.
As an example, look at his lifestyle. Anything that provides immediate gratification is the only thing he chases. Booze, energy drinks, weed, his smokes, porn, the list goes on and on. Nothing he pursues requires some dedication or time.
When it comes to his art, which you’d think would require dedication and time, he cuts as many corners as humanly possible. He doesn’t invest time into learning new things, using new software, buying new microphones, hell he’s been sent new microphones and instead of taking the time to set them up properly he just discards them shortly after unless it plugs and plays. Instead of making things, he will just steal things and place his shit on top of it. Every album cover, tons of songs, every piece of merch, it’s all like that. Whenever he does any of this, it’s not a passion dedicated to art that drives him to finish things quickly. It’s a passion for getting a paycheck quickly, which will get him hammered quickly.
He cannot help himself and nobody can help him. His frame of reference for what “help” is is a passion for hedonistic pursuits and attempting to cut corners anywhere he can. They have their place and time but not for Josh, every day is their place and time.
