Having no set personality

I don’t know if it’s a bipolar thing. Like when I have to box myself into a category I can be anything. Especially when I’m in a manic state, I’m a baddie, flirty, and promiscuous. On the other hand, super nurturing, mother like and reserved. Then super Tom boy like, I can basically be anything anyone wants me to be. And I looove that, but I get sad because i don’t know myself, which is why sometimes I question who I really am.
