I'm not going to pretend I know who you are or the struggles you have endured, but honestly at 19 what do you have to be so depressed about to fail 12th grade? I'm not saying you are doing this, but I've had friends use mental illness (depression) as a "crutch" to justify their lives not going anywhere. Jobless, living with their parents when their peers are graduating college and starting their careers. I mean in a situation like that, anybody would be down in the dumps. Luckily they got themselves out of that rut not because they started self-medicating their "depression" but because they grew up and decided they wanted more out of life than what they currently had. You are at the age now where you are able to make your own decisions, but also you have to live with the consequences of those decisions. I think you need to take some time to reflect on why you feel the way you do and really ask yourself is there anything you can change in YOUR life to make the situation better, because blaming others is easy but it will not solve anything.

I only say this because my dad was always on my ass about stuff too. I never listened and lived my life the way I wanted to until it got to the point where I could continue living like an irresponsible piece of shit for the rest of my life and amount to nothing or I could grow up and try to make something of myself. I don't know your dad, but maybe listen to what he has to say once in awhile because most parents want what's best for their kid and contrary to popular belief they actually do know a thing or two about how the real world works. Hope everything works out for you kid.
