Rose is a nice name. Hi Rose!
I totally understand the situation of downplaying everything and not being able to accurately express the inside chaos. The things with "being unfit to front" is that it's kinda true for all alters, in the sense that not one alter has all the abilities and ressources to front 24/7. That's why we switch when we have DID! Usually we switch for the alters who seems to have the best panel of ressources and abilities to manage a given situation.
Sometimes we do not understand why said alter is the best for the job because we do not see the full picture. As an example, if we see a situation as "needing to write an email" when the system as a whole sees the situation as "coping with a high level of stress", we might not understand why a stress-alter fronts instead of a writing-emails-alter.
It's a very big chaos but it eases out with integration and with building the safety of the here and now.
