What type of mental illness does Nina suffer from? It looks like she has schizophrenia. Her mother also appears to be unwell or just extremely overbearing.

    I thought she is just extremely tensed and obsessed with her goal to the point of sickness. No illness per se.

I would surmise that Nina is experiencing a psychotic break as a result of extreme pressure. Her mother shows signs of having narcissistic personality disorder or some other personality disorder.


Wiki says..

The production requires a ballerina to play the innocent and fragile White Swan, for which the committed dancer Nina (Portman) is a perfect fit, as well as the dark and sensual Black Swan, which are qualities embodied by the new arrival Lily (Kunis). Nina is overwhelmed by a feeling of immense pressure when she finds herself competing for the part, causing her to lose her tenuous grip on reality and descend into a living nightmare.

So just like @aman_abhishk said, it was pressure.
