it's ok, everyone deserves to be recognised as an important individual because, well, you are important ;^;
i myself would also question my existence many times esp. in the past when i thought literally no one would care about me just like how no one cared if a worm died or smth.. (do they even die lol)
im sorry if you're going through some troubles rn.. its ok to talk to me if you need anyone to talk to. if u ever feel unimportant just remember tht someone on tbt cares about u!! idk u but ilu and ur existence <3
