I've unlocked a new emotion - the feeling of being heartsick. For me, this has always manifested as a deep ache in my chest, a feeling that I confused with being physically unwell. But only recently have I corrected this, understanding it as a longing for something undefined yet immensely powerful. It's a feeling that transcends mere sadness; it's a sense of yearning for a connection or an experience that feels just out of reach. I think I'm ... maturing?
