We exist on a lifeline....I guess it's because of being of being co-con???

Like, we deal with the present through switching. Like I go shopping, then an Other wants a Powerball ticket while an Other wants eggs or an iPad part- we do it. Its continuous, but as their own life version, we do different things like I like dressing up and putting on make up while the Mechanic wants to go get greasy (yuck) and work on cars, etc.

Is anyone like this? Is this like a normal DID thing, or my special way of crazy???
