Just Argh

have you guys (the ones that actually bother to read this) ever had a "friend" who just infuriates you. one who claims you are their best friend, but any turn they shoot you down, knock over what little confidence you had. or just doesn't care about anything but themselves, they don't care if you are in pain or upset, they just want to make you happy so they don't have to deal with you? well i am stuck with one like that, i don't want to create a fight because i really don't want to handle the repercussions  of that fight. and not only that but this supposed friend wears a mask of innocence so i have select few people who will actually listen to me. if i try and even explain what is happening i just get,

"oh no your making this up cause she would never do something like that"
in response.... OH MY FUCK. i am sick of it. it is putting me on my last legs, and seeing as i am bipolar i am showing a great use self control in not hitting her in the face. i am just sick of it. i am sick of the way she treats me, i am sick of the way everyone thinks that sun just shines out of her ass. she doesn't care if i am hurt, she doesn't care if anything horrible has happened, like recently i told her i would have to put my cat down soon. she just said grow up and get over it, it's not that important you are pathetic for letting that hurt you, you should stop being a baby and grow up it's not like your cat was that great anyway. it is just a worthless animal. remember how i had said i had struggled not to punch her, well it was in this instance when i felt that sudden wane in control. luckily i didn't do anything i would regret. well actually considering the circumstances i don't think i would have regretted it.

so any advice from anyone out there who is wasting their time reading this? lolz im sure there is more pressing troubles out there, but hey, if any of you have any advice please speak up i am keen to hear it.
