I just cant stop crying ?

okay i got an iud last year febuaray about 4 months after my child was born nothing was wrong then........ for a year it was perfect. now i was feeding the whole time so i didnot get a period at all that whole time. as soon as i started my frist peariod when i was done feeding all hell broke loose this iud is trying to litterally kill me it seems the doctor keeps persuading me to keep it in and i want to punch him in the guts so he knows how much it hurts . my conclusion is that...................the reason the iud is so effective for birthcontrole is because it kills any woman that uses it.. i am bleeding to death currently i have cramps so bad i dont want to stand up. i dont even have the energy to go to the grocery store ( a block away ) to get juice for my son thank god i have someone here to help me do everyday things today. the farthest i've walked was upstairs to take a shower then back to sleep. my period has been close to 3 months long this is the longest its been it seems every time it gets longer 7 days at first......... ten the next time 15 the next and now im up to 3 months i have been considering pulling it out myself all day knowing i'd feel instantly better. but i cant do that because my left side hurts so bad that i'm scared it could have broke through my uterus or something bad. my doc seems like a prick. i am aware but in his mind its not serious and he wants to follow the steps like put me on birthcontrol pills also to regulare.........CROCK OF SH()T didn't work for crap just made me gain ten pounds. still sick still bleeding. IM sorry this sounds like im bitching but i am because i AM TIRED OF ALL OF THIS. I JUST WANT TO RAISE MY SON BUT I DONT HAVE ANY F()CKING ENERGY BECAUSE I DONT HAVE ANY F()CKING BLOOD LEFT. i need advice. ps. vitamins didn't help either and my boyfriend keeps asking me why im getting so dumb lately he told me i have alztimers last night. its making me sad. all of this.
