I feel you OP.
I am in a similar predicament.
My family is all but gone. I am far too alienated from the 2 friends I once had to even stand speaking to them. Instead of lethargic I am very ambitious, It doesn't help because everything I pour my love into ends up being shit. My 'youthful physique' is really starting to chip away, not that I am really obsessed about that, but I can physically see and feel the repercussions (especially teeth and eyesight).
Also, employment isn't all what it's cracked up to be. At the end of the day you could just be paying the bills necessary to keep you employed.
