Am I just antisocial???

Me and my SO are both 20 so we're the first one out of our friends to have a child. (due nov 25😀) Our child will also be the first grandchild for both sides. I love that everyone is so excited for the baby but I can't help but feel like I'll be super stingey with my baby. Everyone wants to come to the hospital, my mil already took off working starting at my delivery date, my mom already said she's taking off a week, my friend gets home from college around then and she said she's gonna be over all the time. Its mostly her that I'm worried about. I was in college too when I found out I was pregnant and obviously immediately had to stop drinking so that was the end of my fun. I felt so isolated my last couple months there because all of my friends were out drinking and partying and I didn't feel like I should even go sober because people smoke openly and I know the fumes are bad for the baby. So I guess I'm just being jealous or immature but I don't think it's fair that she's gonna try and come home and play mom for a month and then retreat back into her carefree life. Same with the rest of my friends. And i don't wanna hurt anyone's feelings but I honestly just want to be alone with my baby for a while. I'm also hoping on breastfeeding and I'd like privacy for that. My boobs have been a huge insecurity for me for so long and I can't be comfortable breastfeeding with a bunch of people around. I know I won't have the confidence to speak up and say something so I already feel like I'm going to be annoyed when the baby arrives 😔 But seriously I carried her for 9 months and dealt with all of the pain and I feel like i deserve to be a little selfish and have her to myself (and my SO of course) for a little while. Is this weird? Am I being really antisocial or ungreatful?
