what do you think you are losing, prue?
as for the way you feel your parents think of you, try to not give them all that "power" in the way you perceive your life. (i know it hurts you very much and i wish you felt they loved you. i would wish that for you too but maybe they can't love as you wish they did. i have no idea why tho either)
my suggestion about not giving them the power is a difficult suggestion to do but this is your life to live as you choose. as u already know i filled my life up with good friends cause i was not happy around my siblings and many of the things they did made me know they were incapable of giving me love. it changed my life for the better to fill my life up with good friends and they love me unconditionally.
i hope you feel better soon and know that i truly care for you, dear friend.
try to talk about these things with your pdoc today. i know it will be difficult and scary but in time it will help heal your broken heart.
