Hi. When there's always confusion about who you are you may have DID.
Who you are keeps changing depending upon who you are with and what you're doing and the other parts of you think so differently about the same thing.
Like- it's so hard to answer a simple question -unless you can be just one part and only aware of that one part at a time. It's so confusing to have so many opinions so it's easier to block out the other parts and be one at a time. Then you can answer according to that part.

You have DID when it feels like everything keeps changing all the time. You may have parts that are opposites of each other and do and say things that you completely disagree with. Other people will accuse that you are lying but you're not. How you write and talk and what you are interested in and believe is true, changes throughout the day and it feels like a confusing mess if you try to think of everything all at once (why i can't keep a journal).

These are some of the ways i think you can know that you have DID. Sometimes parts have names and their own friends which is a lot of trouble. You're not able to change their behavior. You lose time- totally forget what happened for part or all of your day and find yourself somewhere that you didn't go.

You forget important things - every day you think back and can only remember part of your day no matter how hard you try to think of it, it's gone. Then later you can be in the same part and remember it again.
When i was in college i had to study at school. If i was home the notes and material wasn't understandable at all. It was like studying someone else's notes and it was too hard (and upsetting) to understand them. At school that were my writing.

You can know you have DID if you have separations like this.

It's good for your T to know that you have DID so he or she can help more. Therapy is like group therapy instead of just one person but only you come. If your T doesn't know you have DID then he might think that you agree with everything you say and may not be able to help with parts that sabotage things that you do or are doing things that are harmful to the body or your life.

i hate labels and never tell anyone the label- it's never worked out positively, people DON'T understand. It's important for your T to know about though.

Take care, ((((((safe hugs))))))
