Whoa, he sounds like a mess! Those sound like some of the hallmark signs alright, but Ellie is right, he will need to get professional help to be accurately diagnosed; BP is a very difficult illness to diagnose, mainly becuase the denial factor is so high, we only seek help when we're terribly depressed, then most docs just throw an antidepressant at us, which send us into more mania, because they don't screen for BP and we can't have them without a mood stabilizer. It's very complicated even once we're diagnosed because we usually need about 4-5 meds (cocktail) to really get better; there are many more facets then up or down with us - obsessive/compulsive among all types of personality disorders, terrible anxiety, even psychosis which all need different types of meds and usually the first meds aren't the right ones, blah blah blah. It takes LOTS of perserverance on OUR part to get it right; it's not an exact science, it's an art! Better have a really good psychiatrist, not a GP to get it treated really successfully and work WITH them. I'm sorry your friend is denying anything wrong, but Ellie is spot on about the denial. If you are VERY close and I mean VERY close, you might say something, but don't mention the word bipolar, he will get really mad. Just say you're worried about him, he seems to be having problems and might want to see the doctor about it to get some relief and help him concentrate better on his business. Some docs will suspect something, maybe if he's really bad they will suspect it and send him to a therapist (which they almost ALWAYS catch it) or a pdoc (psychiatrist). Although he probably wont' go. Sometimes, we have to do something really bad, which ALL of us do if manic that we pay for dearly or lose the people we love due to our outrageous behaviour and abuse of our loved ones before we get help. It does help if all the people he loves say something out of love and concern and word it gently.
Sorry my post is so long, we all tend to ramble too, lol. Besides being up or down, I'm going to post a list of the other symptoms of mania; mania has to have been present to be diagnosed with Bipolar disorder, not just depression.
Bipolar disorder in one word: Intensity
