Some parts stay the same age, and are very confused when their body becomes older. It is hard when your body doesn't look like you remember it. The body doesn't work like parts do, it continues to grow up over time. But there is a saying "young at heart". It means that your age is how you feel you are, not just what the body is. You don't have to grow older, but your body will. And that's okay. It just takes some work to accept sometimes.
Is there an older part that you trust who can help you out? What about your t?
Hope you are well,
xoxo
