Bipolar Illness

So a few days, I'm quite normal and I relax by watching a movie, go for a walk either. Then, later that day, I'll get really depressed and I never know why. Then when it gets worse, I suddenly cry for no reason. As I do not understand at all. I think this is bipolar disease. Some days I'm happy and one day I'm angry, depressed and so on. I studied a bit and I think I am. What are your views?

I am not a doctor, but it sounds like a bipolar disorder. You should get an appointment with a psychiatrist for an evaluation. He or she can properly diagnose you ... and with a correct diagnosis is the correct treatment. Good luck:)!

If you are concerned about your mood I definitely suggest going to a doctor. This is probably the best type of answer you can get here. Nobody is really able to diagnose. Good luck!

It depends. Bipolar is tough enough, you can have extreme highs and lows and be extremely irritable. And sometimes it's like you just go at any time but never reach something or get something of value is.
But to get the best diagnosis, you are the best to consult a doctor or a psychologist. It is really difficult to know if you have a list of symptoms, etc. You can also google.
