This is not necessarily about DID (MPD) but, if you want to look at it that way that is fine too.
Do you hide your true feelings around others or out in public?
Do you ever have an urge to express your true feelings or just want to laugh sometimes or even cry but, feel that you can't?
Look deep down inside for the you that is underneath all of the other you's and see that you's feelings. Do you ever let them out and if so, how does it feel when you do that and what kind of person do you see?

I see a funny guy who loves to make people happy and make silly faces at babies and snuggle puppies and share light-hearted laughter and play and joke around and just have a good time. He also likes to listen and give advice and be there to try to comfort others who are hurting. His sense of loyalty and honor are great and he respects his elders. That's what I see but, it is so hard to let him out sometimes and he so often remains deep down inside.
Do you ever feel that way? Like you conceal your true self?
