First of all, I had no idea an appropriate title for this, so I went ahead and wrote the above. Second of all, if any can help me solve or answer a question concerning on one's health, etc.? So, how can one determine if he or she has a bipolar condition that can damage their physical and mental healths? Or the point of breakdown or eruption to one's mind that can cause his or her own destruction?
Well if he or she is showing signs of bipolar (i am sure you have seen the signs because you wouldn't ask) then i would speak to maybe his or her parents? or someone with authority, maybe a mental health nurse? your friend needs to know its in her or his best interest and you are worrying about them. Usually a person suffering from this doesn't know they are not well. I wish i could give more advice sorry
