That's rough.

It kind of sounds like you want to be there for your dad, but maybe he's just not at that point where he can admit he made a mistake/(s).

I didn't know about the connection between pot and behavioral issues ( do you have these?) But I would suggest that you stop smoking pot every day, if you are. You can end up really out of it. I would try to figure out what matters to you other than smoking pot. It seems like a goal (any goal?) would be helpful right now. Maybe make some friends that don't smoke all the time, if the ones you have do.

As for the job/college thing don't worry- you're not alone.
