advice?

[fizzgig]

sorry for the emo bullshit beforehand

my dad has four daughters (maybe more kids floating around)

i can't stand the two my dad had before me with another woman

i've met them both once and talked to them a few times

they want nothing to do with my father, a man who plays father to all those who don't have one, a man with so much love it boggles my mind (i may be biased because he's my dad, but he loves anyone who needs it)

my dad has tried so hard with the two of them and it breaks my heart to see the hurt he won't vocalize about the two of them

not too long i told my dad he better specify in his will what they will get, because i won't give them a damn thing (i know that was a hurtful thing to say, but my dad and i don't hold anything back)

is it wrong that i hate and resent them?

how can i be a better daughter to the man i love more than anything?
