Crying all the time...

Is it possible to change your chemical make up without medication? 

I need to do some research on this subject.

I'm way to emotional.  Most of the time for no good reason.  I cry when confronted...even if I'm completely in the right.  I cry during songs.  I cry during movies.  I cry when reading greeting cards.  I have even felt myself starting to tear up at work meetings.  (I fight those...I actually try to fight all of it)

I feel like I am a strong person.  I have been though some crap and came out of it ok for the most part.  I was in an abusive relationship and didn't cry this much.

Wikihow.com https://www.wikihow.com/Stop-Yourself-from-Crying says you should do the following to stop yourself from crying easily...

Method 1 Stopping Yourself from Crying with Physical Actions

• Focus on your breathing.
• Move your eyes to control your tears.
• Distract yourself with a physical movement.
• Relax your facial expression.
• Remove the lump in your throat.

It goes on to say that changing your focus helps.  Thinking of something funny.  Remind yourself that your strong (that would probably make me cry...when I'm feeling emotional I can't think of me personally...the crying always gets worse then). 
Blame your tears on something else.  I have actually tried that one..doesn't work for me. 
Dry your tears discreetly (also doesn't work...when I cry I FACE CRY...there is no hiding it)
Remove yourself from the situation.  Most of the time not possible.

There are several other methods listed in this article.  I might have to delve deeper into some research.  I really need to find a solution.  A way to stop this crap. 

I don't want to be emotional.  Its alike I feel everything sometimes but I really just want to feel nothing.  And its not like I care about everything and everyone...I literally don't. 

SO that also makes this more of a mystery. 

So basically I don't think there is much I can do.    I shall continue my search.

Can you offer some words of wisdom or advice?
