My brother likes to complain about how horrible his life is yet if anyone asks if he's tried therapy,tried reading certain books,medication,whatever,he has excuses such as "I'm messed up".

Maybe deep down he wants to change things but how's it going to happen if he doesn't even try?Nobody can change things for him,he has to do that himself.It's frustrating listening to someone complain all the time yet give nothing but excuses.
