Would this brand new car be the one you wrecked, this $75K job the one you lost? Are you driving around drunk and stoned all the time? Everyone's watching you like a hawk, and it's only going to take a single misstep for them to throw your ass in jail.
Regardless of whether you pulled some drug-fueled body heist, you need to stop this crap. If you can go from homeless to where you were before all this happened, that right there is more impressive than the star-crossed-martyr-detective bullshit.You've made it clear that it's not about Julie would have wanted, because if she cared about you as much as you say she did, I doubt she'd condone your self-destruction.
Just stop.
