i did kinda?

basically i knew a girl and it was middle school. we werent in the same class, but i would talk to her in the hallways and at lunch. we weren't close, but i do believe we were friends. i literally was hanging out with her at school the day before she died. we never really hung out, and it was the height of covid, so we said the next day we would watch a movie on zoom together. the next morning im in the living room and my mom tells me someone in my grade paseed away, when she said her name my heart dropped. i was so sad about it, and several years passed. im now a senior and i feel like a terrible person. im still very sad about it, but i feel like an imposter. i wasn't close to her and i shouldn't be so effected. i would love some insight because i jus want to vent. like when someone brings about death i bring her up becaause shes someone i knew that died, and none close to me has dead (thankfully). i just feel like heartless stuck up bitich who should keep her mouth shut about something and someone she don't know about that much. idk, i can't afford a therapist
