Our Old Multiple Personality Disorder Confusion

Step by step I discovered myself, my needs, what I do and what I don't wanna do, in what circumstances I will be forced/pushed to do something. What happened is that I use this information, or it's more honest to say I misuse this information to deal with myself and try to make no problem when I live. There are definitely more than 1 person in me (2 or maybe more) but I can not really recognize the borders.
