About  10 years or so I have struggled with my mental health. These past few  years have been extra hard on my psyche for countless reasons: friends  dying, no job and its been hell trying too start studying because of my  own discouraging. I have been "sad" or "under the weather" for so long  it feels like nothing will ever work out. Crying has been one of the  very few constants in my life recently but for some time now, whenever  something bad happens or I get some very bad news from someone, I just  feel empty and don't even know how to react anymore.

My question is as simple as the titel says, why don't I cry anymore?

The closest I have been too crying for a very long time is simply  feeling the tears build up inside but as soon as that happens its like  some kind of button is pressed inside my brain that just cancel it all  out and I instead just sit/stand or lay down without any reaction  whatsoever.
