Re: I screwed up big time
The things you mentioned about your parents not appreciating your achievements and emotionally blackmaling you, bring you down,etc.. it happens all the time. In fact it’s happening right now with me 
no biggie bro, it’s just their mentality.
anyway, I can’t really give you any advice cuz im in my early 20s.. as far as your whole concern with the rat race..etc, find a job you love to do, it doesn’t have to be a high paying job, just do it for some time, get your mind straight, pay off your debts, find a hobby, join the gym, live YOUR life.
and as for the relationship with your brother, maybe others can share their personal stories you can learn from..
