No tears left to cry (literally)

Have any of you ever felt such an overwhelming amount of sadness, that you could literally feel your whole body acting up, but are unable to cry? Maybe I’m just overwhelmed? But idk by what. Is this seasonal depression? Maybe it’s because of my personal life and academic duties. Well, all I know is is that I want to cry and scream at the top of my lungs but I’m unable to. Why can’t I cry when I feel so dreadful. I had to watch sad videos the other day because I wanted to cry so badly but couldn’t. Am I just being dramatic? Probably. Honestly, idk.
