To be clear, being hyper-logical is a sign, and usually also a symptom, of depression. Hyper-logical people do not tend to have normal levels of pleasure, as being hyper-logical is usually a coping mechanism for stress.

@Ichi, I'd say you're sociopathic, which caused depression. From everything you've described, you're either incapable of, or have forced yourself not to, feel certain emotions. In other words, what you've done may actually worsen your depression.

As I've already stated, one cannot easily "control" chronic or severe depression. It has caused a chemical imbalance. At that point, it is no longer a mental issue, it is a biological one, and a person should seek medical help.

Damn. Since when did you get a degree in psychology?
