I'm actually not too aware of what I'm feeling for the most part. An INFP might say he/she is sad or happy and perhaps use a simile. I honestly have to think about it before I know any emotion, except, I guess, when I'm angry. Sometimes I'll start crying and the shock is overpowering. I mostly live in the world of thoughts. I spend a lot of time thinking about creating things and the future and how I want to be famous some day. I have a knack for attributing my over-excitement to happiness instead of mania, which I suffer every now and then.
