(Sorry, I'm not really an author... I like lurking here. However, I think it would be cathartic to write here, even if no one responds)

A tadpole very clearly belongs in the water. A frog very clearly belongs on land. However, there's a stage inbetween where the tadpole still has a long body and tail, but also has all of its limbs.
I feel like a tadpole with limbs. I'm married, we live on our own, and are expecting a baby. I do the things of an adult. Except, I'm only 18. I'm still a kid, and no amount of responsibility and good decisions is going to hide the tail that suggests I should still be in the pond with the other babies. The limbs seperate me from the tadpoles, but my tail keeps me from the frogs. I'm in an emotional limbo. No amount of playing frog is going to suck that tail away, only time will. No amount of playing fishie will retract my limbs, and there's no going back now. I don't belong anywhere. All I can do is wait until the other tadpoles catch up or until the frogs can't see my tail anymore. Either way, I'm all alone.

I don't regret my decisions. I've honestly never been happier in my life... I've just also never been as lonely. And I don't see an end to the lonliness. Not until my tail shrinks or the tadpoles catch up.
