Am I being petty?

I have placenta previa and have to have a C-section. I used to work at the hospital I'll be giving birth at. I was a surgical services assistant and I was bullied HORRIBLY by the surgical techs there. It's why I left. I know they have a surgical tech or two during a C-section and I spoke to my OBGYN about it and said I don't want them seeing me vulnerable. He said he understood and he could have someone else there with him or even just the surgical manager and she was amazing! I love her. He said he understands and I shouldn't feel more uncomfortable than it will already be. I felt grateful. My mom said I'm being petty though and they are professionals and I shouldn't be letting some old mean girl behavior let me think they won't do their job. They treated me badly. I don't want them being there to see me naked and get cut open but my mom says I'm being a baby and need to grow up y
