I have a cousin who was diagnosed with bipolar disorder. She has manic episodes.
Oh no :( Bipolar disorder is a mental disorder that causes periods of depression. I can't imagine having it. It must be hard
Yes I believe she has medication that helps stabilize her mood but it definitely affects her quality of life.
I'm sure. During episodes, those with bipolar disorder usually have abnormal levels of energy, happiness, depression, or irritability. I assume it's rough to try and stabilize your moods
Hopefully one day scientists can find a cure for Bipolar disorder, as well as other mental illnesses.
That would be great as people with bipolar disorders often make poorly thought out decisions with little regard for the possible repercussions. That could go very badly at the wrong time! 
Yes, they "live in the moment" and don't think about the future. It is too overwhelming for them to process.
Also, they don't feel the need to sleep as much during episodes which causes even more stress and irrationality. Anyone who has stayed up for 24 hours might have a glimpse of what that can be like
