CF by choice, but still feeling left out

I've always known that I don't want to have kids; I've never seriously considered having kids because I just know that it's not a lifestyle that I want. My attitude towards children in general is neutral.

However, now that I'm at the age where my friends are having kids, I feel a kind of sadness or loss in the sense that our lives are diverging in this irreversible way. Not that I feel like I'm losing friends (only one relationship has really waned), but more that I feel like they're experiencing a part of life that I'll never have access to. Again--not that I want access, but I guess I do feel like by choosing not to have kids I'm missing out on part of what life can be.

I see that my friends find purpose in life by raising their kids and building their families--fair, I'm happy for them. I just don't feel like I've found my purpose yet, so in that sense, I feel like I'm trailing behind everyone else.

Is this relatable at all?
