Not based on what you list. Depression has many more symptoms than just feeling sad. Mania has many more symptoms than just being happy..... those are just emotions.
And just fyi... it is not called Bi Polar Depression. It is Bipolar Disorder and the more important and more destructive part is the mania..... You don't even have to have depression to have Bipolar 1. Just mania will do.
But mania is serious and dangerous and ruins lives. You are perfectly normal.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
