Grieving after having your tubes tied?

Hi!! I'm in my mid 20s, and I'm 100% sure I don't want to have kids. I've never wanted to, I don't want to, and I won't. I really like kids, I like teaching, but I don't want one of my own. That being said, the societal pressure is huge, and I feel like I'll be seen as less of a woman somehow if I get my tubes tied? It's a crushing feeling and now that I'm seriously considering getting my tubes tied in the next couple of years, I feel like I'm somehow grieving, even if I'm 100% sure it's what I want to do. I'm not scared of regretting it, but I still feel this wave of strange sadness anyway. I feel like I'm disappointing someone. It's weird.

Have any of you gone through this? What was your experience?
