how much, is ever enough?

Recently, I've been trying to change my thoughts.
They say, if you can't change what's happening, then change your mindset.
I want to be more positive, and the effort is taking a more daunting task than i thought.
Change never comes easy anyway, it goes through failure, withdrawals etc
But, i really want to be more positive, be more strong mentally no matter what comes my way.

Only... I feel like i lack a proper support system.
Honestly, I would love to have someone who understands what i'm going through to talk to.
But i don't. No one around me understands or is ever there for me.
I try, to lower my expectations.
But how low is it ever enough?

Sometimes, (and this is the pessimistic side of me talking again), i feel that the world won't care if i just die.

Yeah.
