I've no idea about the depression part - I've had good times and done good things? I'm sure it's fair to say that most people will have mixed emotions throughout their life...?

As for Bipolar, sometimes I feel a some what violent urge to do something - but I put that down to heat of the moment and never do anything as a result of my thoughts.

As for personality disorder, I honestly have no idea and my ability to read through them all would definitely be tested.

It might be good to add the fact that my father and his father have both been diagnosed with schizophrenic type illness but I didn't want to add that to give an unfair judgement. As far as I can tell, my father's father killed himself and the illness runs in the male side of the family.

Obviously this could mean nothing, but I thought it might be worth a mention.
