on emotionally growing up

Growing up is the process of the individual trying to control their emotions.  Human emotions are intense, overwhelming and ALWAYS with us when we are children.
 As we emotionally grow we learn the falsity of these emotions. We learn what to expect from ourselves when we are exposed to certain stimuli. We know what we will feel and think and we can stop or limit ourselves from experiencing the intensity of anger or sadness or whatever. In fact we actively seek ways to do this in order to avoid temper tantrums, as that is not normal adult behavior. Or we can anticipate a positive emotion and exploit it for what it's worth: when we enjoy the company of another-we can exemplify those positive feelings towards another person and mistake it for love.  In the end, we control our emotions.
But in some cases a person does not emotionally grow (perhaps in more cases than not). A person might never lose the intensity of some emotions or might never exemplify others.  Are their emotions more real? Is the person who fails to grow emotionally experiencing the truth?
