In some traumatic situations, your brain might naturally shut off emotions to cope and to avoid danger, kind of like right when you injure yourself you may not feel much or any physical pain until a day or so later. So on one hand, I would say it's okay to not feel really emotional, sometimes... on the other hand, I'm pretty sure every single human being on this earth has emotions, and that's normal.

You have some mixed messages in your posts. Sometimes you claim you're naturally not that emotional, and then you write things like this:

So from that it sounds like you're expending effort on suppressing emotions. Suppression is unhealthy. If you suppress something long enough, it will build up until it eventually explodes. I don't know you personally, and I myself am a highly emotional person, so I could only speculate why you would want to suppress emotions... whether because you're afraid of honestly expressing yourself to others around you who might reject you... whether you judge emotions as a sign of weakness and inferiority... or because it's safer to not open up deep past traumas until you can handle it.

Being naturally logical is fine. Forcing out emotions all the time, in every situation? Probably not. I also take issue with your entire perception of history, evolution and societal "success". Yes, the bravest people are generally the most successful, but bravery does not = no emotion. Bravery is having emotions, having fear, insecurity, love, anger, etc, but choosing to take action independent of those emotions. Also, it really depends on how you define "success". In a capitalist, patriarchal society that only values masculinity and not femininity, maybe that mentality prevails, but many rich, famous people like actors, actresses, authors, athletes, or even Oprah, are openly emotional and in fact celebrate having emotions. If emotions weren't natural and healthy, humans wouldn't have survived through evolution still being this emotional. Clearly, it serves a unique purpose.
