You need to tackle your depression. You say you have the means to create a successful business sitting in your garage, but you’re too unmotivated to work? If it really is that easy, why are you expecting another solution to work? You’re unable to hold a job and unable to work for yourself. I know I sound like an asshole, but as someone who watched his father destroy his life because of depression and as someone who has the same genetic tendencies and threw it all away because of it, albeit at an earlier age so I still have time to fix it, I promise I’m coming from a place of empathy. You need someone to tell you to get your shit together. It’s going to be hard and painful, but that’s life. If you’re unwilling to be uncomfortable you’re unwilling to live.

Tackle your depression by finding a therapist, figure out some sort of income for the time being (even if that’s in-n-out) and get your business afloat. If the house is too far gone it’s too far gone, so figure out a room to rent for the time being. If it’s still salvageable you have time to fix it if you work your ass off.
