It depends on how you are doing it. If you just want to be somebody else for a little while and you know it, then no. There is a mental disorder called Multiple Personality Disorder, and it is where the person actually has split personalities and is being more than one person, but they don't know that. So it depends on if you know it or not, and what you are doing.
Yes, it is. It has a special name called Munchausen Syndrome. It is a mental disorder in which a person repeatedly and deliberately acts as if he or she has a physical or mental illness when he or she is not really sick. Munchausen is considered a mental illness because it is associated with severe emotional difficulties.
It would depend on the circumstances. If nothing else it is lying, unless you are an actor playing a role.
no, it is an attention getter, sad to say these people need some TLC and find out why they are doing that.
Because Bipolar is a mental disorder. What else would they label it
No more than any one else.
I would probably think to "ignore" someone is a word that means that someone is pretending not to listen to someone else.

Generally (because the question is somewhat vague), it means pretending to be someone else during the commission of or with the intent to commit a crime. For example, pretending to be a police officer and stopping someone (unlawful restraint); however, pretending to be a police officer while delivering a stripper-gram would not be criminal as there is no crime committed or intended. It doesn't have to be a police officer, though, it could be a normal person. For example, pretending to be someone else so you can take money out of their bank account, even something as simple as using someone else's ID to buy alcohol.
If she really loves you, act like yourself. By pretending to be someone else, she is not loving you for who you really are.
