@asiangal555,
First of, you are who you are. While it's never a bad thing to try and better yourself, I suppose, don't be too quick to follow the advice of others in regards of what is perceived as flaws in your personality: There are bound to be people out there who like emotional persons.
If you can't seem to find any, perhaps look in other venues than the ones you are currently using.
However, if you really do wish to try and become a less emotional person, I guess you'd have to stop wearing your heart on your sleeve. Probably takes some practice to get it right.
