How do I overcome sad?

When I have meditated lately there have been a few times where I felt like I was going to cry, tears welling up to the midpoint of lungs but stopping there. Like that almost throw uppy feeling but you just can’t get rid of it.

People at work are starting to treat me a bit differently. Some say I have been distracted or ask what is wrong. Or have given up on my irreverant flip sense of humor.

I notice all the pictures I am in look profoundly sad. I can’t look at one without being startled and put off. And I avoid long dates with friends and family because it just too stressful for me.

I am tired of being on the brink but can’t push past that point. I have asked myself what is holding me back. And I can rationally think of nothing.

It feels melodramatic. I realize emotions aren’t rational. I don’t know how to get past this phase. But it’s not fun and i have no idea what direction I should go. I have tried anything from surrounding myself comedies and fun to trying to wallow in it and be done, with meditation tanning and exercise thrown in for good measure. I end up in same place.

Has anyone been through a similar experience? What is there left to do?
