Ever thought you might have multiple personalities?

My worst fear growing up was that i had DID or some closely related ailment. I often loose time when stressed and sometimes feel like another piece of my psyche is taking control, though except for my time lapses “I” am always present i just feel like a new person or seem to watch myself do things i generally wouldnt do. I have 3 or 4 distinct personas in my head but my therepist tells me that its perfectly normal. He had me do some research on “parts theory” where split pieces of a psyche or different personas are still part of a “whole” person. I dont worry so much about it anymore although loosing time is generally an upsetting occurrence and still scares me quite a bit.
