Baby shower troubles

I’m so anxious about my baby shower. My friend offered to be a cohost along with my sister and I asked for it to be at my moms house. My moms house is pretty big, cozy and beautiful and really all I wanted was a low key, intimate and comfortable shower because I get very nervous in big groups and trying to impress people.

Well the shower is coming up this Sunday and I’ve somehow overly inserted myself into the planning process. I think because a combination of 1)I don’t trust my sister and friend to plan it and 2) I feel bad having people plan something for me

I don’t know where these control issues are coming from, I’m truly not normally like this. The RSVPs have shot up to 34 people and I wanted to keep the guests attendance under 20.: Dont even know how that happened! I should be grateful that I have so many people who want to shower me but I am honestly overwhelmed and nervous and find myself stressing about things that I don’t even have any say in like the amount of food, etc. Also feel fat and I’ve been sick, can’t decide on a dress to wear.... why do I even care how my closest friends and family thing I look?🤷‍♀️ I’m nervous about the theme too and the games we picked , just overall being a psycho ugh

Am I the only one being this neurotic?? I just want to enjoy my shower and trust it will be fine!
