To feel like i'm a doll in terms of my emotions

In terms of my emotions, I often feel as though I'm a doll. The people playing with me (a doll) are events and such. When something happens, it almost seems as though I default to one of six emotions. The emotions are as follows: Happiness/joy, sadness, anger, apathy, fear, hope/faith.

It bothers me because all of my emotions seem to be rudimentary or bare bones. It seems as there in little to no grey area. One of these five emotions always seems to be present.

One other thing to note is most of the time my emotions are to the extreme. For example, I am a highly faithful and religious fellow. When I am sad, I almost always will cry. When I'm angry I tend to hit things (in a controlled-ish way. Always in an isolated place. I can bottle the anger almost all of the time), etc.

I can't help but feel that my emotions being to the extreme and almost always very simple is an issue. Anyway, thanks for your time.
