medical authority?! pfft!!

okay i have never posted twice in one day but I'm really angry and hurt. i have a friend who is going to school for medical stuff not nursing or anything but i feel like since i told her I'm pregnant she has felt like she has to be the the medical authority on everything she tells me things even when i don't want to know and she goes off on things my doctor should have done. apparently in his 30+ years of practice hes been doing all wrong. he delivered me and i got here fine. i tell her I'm not worried about it and that she should let me be the judge of my doctor that she has never met nor will she ever. it really makes me angry i love my doctor hes amazing and I've never had a problem with him. i will defend him to the death. just because my Dr doesn't do it the way she learned about or the way her doctor dose it doesn't mean that its wrong. i trust him completely. i really am upset by this and it stresses me out i want her to just let it go i don't even talk about my visits with her anymore because i cant take the flack. it makes me sick and me and the baby (babies) don't need that crap. I'm not even sure i want to be friends with this person any more she causes me more harm than i think a friend should but I'm not sure i want to not be either  it its hard for me to stop being friends with someone just because they hurt me. i know it sounds dumb, i forgive to easy sometimes and i let alot go. i tend to just let things happen over and over again even though they hurt and upset me i hate causing fights it makes me have panic attacks so i avoid it and that makes me keep people who normally would be cast aside i need to learn to get over it and stand up for myself  i find that hard to do with everyone i would rather they think they are right or make themselves feel smart or better then tell them they are wrong and to stop. i try not to worry about it but this time its not gonna go away she is unrelenting  I'm going to have to be mean at some point but i really don't want to i just want her to not talk about it. is that so much to ask to keep your nose in your own business really that's all I'm asking for! sorry for ranting i really need to get i out of my head its been bothering me for a while.
