I am sad but I am not

What is it in me?

I feel two emotions at the same time..
I feel happy and sad about a situation..
I feel annoyed and joyful about something else..

I know I am weird. but this thing is crazy.

Funny.. I could also get into an emotion
When I should not
for example… I cry for no reasonat all…
I am just depressed
I am angry and annoyed[most of the time] but there is nothing to be angry about.

am I crazy… maybe, I am
