on being ignored

i work with people whom i admire, love, and respect, yet i feel like the red headed step-child, no matter what. all i am is nice,quiet,and compliant. is that all that i am??? why do i even bother? if i died, no one would even care..i feel i am expendable. why can't i be important? i know it's stupid but i want to feel valued. i'm not cool. i'm growing older,and feeling more and more irrelevant. no matter how hard i try to reach out to people, i am just not cool enough to acknowledge, i don't have the "stuff". if they only really knew me. if they only gave me a chance! they might like me a lot!
