Not a professional here, only expressing my humble opinion:

No one single action or even series of actions can warrant a person psych diagnosis. What can then? In my opinion it's presentation of the said action. For example may people shop excessively, but when I was manic I spent every single sent I had on me atm. I bought very nice things that I still use and like BUT I didn't need and couldn't afford them at that time.

Hypersexuality and need for attention are very common for women. It's not sick too enjoy it, but if this enjoyment brings suffering to others (example: with husband present and at HIS work party) it is not really OK to do. And if a person fails to recognize the results of her actions, something is probably wrong there. Especially if it's not her usual way.

SUI is a special topic for me, since it happened in my family due to an untreated mental illness. My view might be too harsh and not very academic, but it has proven true (for me) over years. I believe that if someone actually attempted sui there was a mental illness present, even if the circumstances of life were hard and there was significant stress. Even in German concentration camps majority of people fought for life to the last second, not because they particularly enjoyed it at the moment, but because healthy survival instinct is too strong and hard to kill in a human. But if it's broken, any stress, even relatively mild, could push a person over the edge. I think anyone who ever attempted should take preventative measures before stress strikes again.

Examples could be endless but not to make this post too long I will just summarize my idea. BP psych dx is only needed and useful if behavior is bringing suffering and is to a detriment of a person's life but he is unable to understand the consequences of his actions or is convinced that there will be non, even after it becomes apparent that there will be and grave ones.

If I doubt my sanity I usually ask myself:

1. Was my behavior prudent?
2. Did I fully realize the consequences?
3. Would those consequences be apparent for me now?
4. Was it like "me" to act that way?

If answers to the most of them are NO, I wasn't really in the driving seat.
