What is dissociative identity disorder?

Dissociative identity disorder, or 'multiple personality disorder', is the most extreme of the three types.

If you've been diagnosed with dissociative identity disorder, you may feel uncertain about who you are and struggle to define yourself.

You may feel the presence of other identities, which may each have their own names, voices, personal histories and mannerisms.

Typical symptoms are:

  • feeling like a stranger to yourself
  • being confused about your sexuality or gender
  • feeling like there are different people within you
  • referring to yourself as 'we'
  • behaving out of character
  • writing in different handwriting
