It feels really weird being an adult alter in a minors body. While the body is 17, I, a fictive and protector who is 24, feels...really old. Sure, it's only 7 years, and I'm not the oldest, but I'm close to it. Most of the other alters are 12, 15, 17, or have a non-specific age, but only 5 of us are older than 20. It just feels really, really weird.
Oof yeah, we definitely feel this! A few of our parts are older than our body, and many of us are much younger. As we get older, that age difference becomes less of a big deal for our older parts, but much more stressful for our littles.
We’re sure this is a problem that lots of system members face in all kinds of systems! Just one of the intricacies of being plural. We hope things get easier for you as time passes, though! Wishing you and your alters the very best in your future!
