I’m sorry to hear you’re having some problems. Feelings are an important part of us, to suppress them can have negative impact on a person. There are things that make people want to cry, including music/lyrics, sad books, and even seasonal depression because of getting less of the suns vitamin D. I’m not saying that is why for you necessarily, I am no health professional, so instead I’ll share some with you.
Unless a song’s lyrics really speak to me, it doesn’t usually affect me too much, but for some strange reason the violin does. No lyrics required, and even though it can sound beautiful I find it also sounds like it is crying and really chokes me up at times. I also don’t often cry when I hear bad news, but I feel way more emotionally overwhelmed when I hear a person selflessly did something good for someone else… ohh also animal videos, but I’m pretty sure everyone is like that with animals.

I know it is very awkward for people crying in public, even witnesses, but crying is healthy. Someone told me once that you have feel your feelings, and it kind stuck with me. So feel those feelings and I hope the rest of the night goes well.
