I definitely matured A LOT emotionally over the last few years in particular. A basic timeline (my memory is bad so bear with me):
- Childhood: I don't remember much of it, just little glimpses, but I'm told I was a monster with a lot of outbursts.
- Teens: Still a monster and with teen issues on top of it, but less emotional outbursts. Outbursts had more of a reason than before too.
- Late teens: A more mature monster, starting to get a better grip on my emotions, but still far from normal reactions to things going wrong.
- Age 18 to maybe 23: Emotions got to be less and less. I started "perfecting" the art of faking socially to get by (previously I couldn't even fake it, I had very little filter for my words and actions).
- 23+ (I'm currently 29): I felt less and less emotional as time went on. Those few emotions are rarely shown, it takes a lot to get them to appear (but it's not healthy when they do). Only in times of panic or severe depression do I find it impossible to appear emotionless or fake happy.

So in 29 years of living I've almost done a complete 180, going from uncontrollable emotional outbursts to having very few emotions.

What has helped me the most is being very self aware. It seems like you are to some extent as well, so that's good! I've had to learn the hard way sometimes, but at least I'm learning. I still consider myself "socially retarded" because I don't understand some basic hints most people use and need people to be up front with me when I'm doing something wrong. Between losing people due to my emotions and reactions or actually being told I was doing wrong I've done more for myself than any of my therapists have. Still have a long way to go though.
