What do you think about me peeing myself in bed until I was 13 years old?
Why did you have to keep peeing yourself for that long?
I was afraid of making noises while taking a shower
I'm sorry you had that sort of fear, but it is unhealthy to keep wetting the bed past your childhood. There must be some big trauma underneath, and you should get that sorted out before you need to always use adult diapers.
My parents don't know. It is also no big deal.
You're fine at this point since it already happened, but it is definitely not normal to wet the bed so late into life. You should go speak with someone about this, now.
