Please read this and please help me.

Today me and my boyfriend went in to see my GYN for me to get an IUD. She told me that it was going to be painful but that the pain would eventually subside. My whole life i’ve been told that i have a super high pain tolerance. even as a child. If something ever happened to me i wouldn’t cry. I would just get over it. I am a type one diabetic so I spend all day sticking needles in myself. I’ve had needles put all over my body, Including a giant one into both of my wrists... perpendicular to my arm. I once broke my ankle while camping. and then right after breaking it.. had to walk a mile to my car while carrying probably over 50 Pounds worth of stuff. All of this hurts but it’s just pain and I just deal w it and then get over it. But today when I went in to get my IUD...I had no idea what i was in for. I was screaming at the top of my lungs. I was crying my eyes out and shaking so much that both my boyfriend and my GYN were holding me trying to prevent me from passing out. I was in there like that for about half an hour. my boyfriend had to check me out and drive me home. it’s been 5 hours since my appointment and I still haven’t stopped crying. the moment of Feeling that immense pain keeps running through my mind and I just can’t stop crying. So I wasn’t able to get the UID and my GYN said that it was no longer an option because of how sensitive my cervix is. I feel so beaten down. I wanted to do this. And now I hate myself that I couldn’t. And now I’m thinking i might not be able to have children. I raised myself and since I was little all i’ve ever wanted to do was be a mom. Because through not having a family I learned to envision who i wanted to be and become it. All i’ve ever wanted to do is have children and raise them right and love them. It’s all i’ve ever wanted. I am a full time student working my ass off, not for me, but so that i’ll be able to raise my children with adequate money. so I know that i’ll be able to provide for them. But to be 100% honest, as much as it hurts me to think and say this... i don’t want to have children if it means i have to go through that paint again. Has anyone else ever had that IUD experience and then went on to have kids? what was your experience. I didn’t even know pain like that was possible. Is it possible to ask to have a C-section? Can you tell ur doctor that you don’t want to do natural birth? I don’t know what to do. Some one please help.
