Just want to hear thoughts

Is it normal to still dwell on past bullying? (My bullying was 3 years ago) On Friday, I was made fun of the exact way I used to be made fun of back then, and now I genuinely don't want to return to school because of it. If anything, I feel too scared to return to school bc of it. What if I'm all alone and they come up to me making fun of me? What if they record me and post it and make a bunch of stickers or wtv out of me. Idk anymore, but every time something that reminds me of my bullying experience happens, I don't want to do anything anymore, like I genuinely want to go mute I don't want to be seen or talked to. I don't want to be acknowledged, I want to stay in my room as much as I can.
