Some stuff nobody cares about

I worked yesterday, and one of the people who came in was an American girl. For the most part it was all normal, but near the end of her visit I got hit with a wave of sadness and loneliness remembering Olivia who I was talking to on here and Instagram in like 2020. I didn't realise I still missed her at all, and hadn't thought about her since she broke things off kind of randomly and without giving a reason. I'm still struggling a bit with the lingering sense of loss and loneliness over it, even though I'm unsure why.
