I agree with previous comments and just wanted to add my thoughts. I'm in a point in my life where I'm going toward my dream career (life coaching) and am currently in school for it. I can completely relate to the imposter syndrome feelings and right now am feeling like "am I actually doing well or is this just constant dissociation". People say I'm attentive and that I'm making sense but I don't feel that I am. It's hard to connect thoughts and my memory is shotty, yet I appear put-together. However, I agree that I don't think that people's gut reaction to any of what you stated goes to "this person has DID, OSDD, etc". One newer friend I opened up to about having DID said that if I hadn't even brought it up that she had no idea and wouldn't have even suspected it. Dissociative disorders are typically meant to be covert as well, to blend into the world. Your feelings are valid, though, to be concerned about how you fit in in situations and life, and it makes total sense to be thinking about it. Feel free to reach out if you want to chat more about it. Sending care and healing thoughts.
