Struggling with expectations

I’m scheduled for a bisalp next week. I’ve had a couple sessions with my therapist to help process my feelings about all the things, so I guess I’m just looking for encouragement? Reassurance that I’m not the only one going through this?

I’m 26 and felt fairly confident my whole life that I didn’t want kids. I still stand by that but I think the bigger thing for me is not wanting pregnancy. I spent years trying to get approved for a breast reduction and am not at all interested in pregnancy reversing my reduction. I’m not interested in the pain and discomfort of pregnancy and birth. I don’t find babies particularly endearing and don’t have any desire for one of my own. Not interested in passing on my genes. And it feels selfish to me to have kids for the sole goal of having someone to take care of me when I’m old. I’m not opposed to kids as a concept and would be open to considering adoption or fostering if all the pieces fell into place, but that’s so far away and doesn’t affect my disinterest in pregnancy. But I’m really struggling with the societal expectations and the opinions of my family and friends. No one in my life is going to disown me or anything over this decision, but I’m also not receiving the support I really would’ve appreciated. I have terrible anxiety, and I’m finding myself spiraling and terrified that I’m going to get left behind by my friends and family as their lives change and they get married and have kids while I don’t. I truly don’t think I’ll regret the bisalp for its purpose, but I guess I’m afraid of regretting the social consequences and what it will mean for my relationships in the future. This procedure is something I’ve considered for several years but the timing is a lot sooner than I ever intended it to be. Just in terms of finances and my health insurance it makes sense to do it now, but it feels so much faster than I anticipated.

Edit: I’m truly so grateful for everything y’all have shared here! All the encouragement and reminders to listen to my own wants and needs are exactly what I needed to hear. And it helps a lot knowing that all of you are thriving and happy with your decisions even if you had similar doubts and anxieties like I’m having now. Thank you so much!
