ive been having very sudden emotions and physical pain and tears?

[little_lost_one]

When someone says something suddenly or unexpected or even remotely harsh, I immediately feel pain in my chest, like the sudden weightlessness of falling off a cliff and the pain reaches outward out of my chest or up in my throat. I start having very runny uncontrollable tears and as soon as the wave of emotion ends the tears stop and the sinking feeling becomes less prominent like a numbness. If I remember the thing again the whole cycle repeats itself and it's painful and difficult to explain. I was depressed a d suicidal four years ago but haven't been since. I'm 16 yo and I'm not sure what's wrong. This has been happening for the last two years but only at specific times, lately it's gotten worse and much more frequent. I'm not sure if I'm just over thinking it but it's been causing some trouble in social circles and the like because it's so abrupt and otherwise absent.
