no offence for saying this but seriously i think Sk you should get a grip of yourself!
if you have already given up on yourself, what more about others?

so what if your life is in a mess.. so what if your cupboard is in a mess.. your family is in a mess..
like so what??
all the complaints wont get you anywhere isnt it?
just take a deep breathe... and pick up the mess!

since u say your room is in a mess. den u should start clearing up!
all the clothes dat you haven been wearing just chuck them away la!
since your father dont washes your clothes properly, den wash them yourself lor.
if they wan to quarrel.. den let them be. (wat can you do right?)

since you are financially tight...
you should start prioritising on what you are spending!
if you cant afford den don't buy!
if you are wanting something badly, den start saving and less spendings.

you can go on and on with your complaints but all these shit will remain where it is.
if you think negative, everything else will also appear negative.

how you wan to lead your life...how you wan to see your life..
is up to you yourself.
