NO EXCITEMENT

am really pissed off right now and i really don't know what to say!! i feel like being taken for granted.. i know am not part of their family nor relatives but i seems like, they're just thinking bout themselves.. what's more applicable for them.. what's their best time.. no matter how i tried to understand the situation, i don't know.. am just the bestfriend and i should not give a damn but hey, am working and its not easy for me to file a leave of absence.. 1st time changes is okay.. 2nd time, enough.. 3rd time is too much! and i know my bestfriend is hurting everytime i say something bad.. but wut bout me? is always like this.. i feel like am a piece of crap.. damn it..
