This is a quote from a Taylor Swift  song but I forgot the name. This line meant nothing to me before but now, it means everything because I now know how it feels like to lose all your friends and even though it's a full class, everyone is chatting with their friends and you are sitting in your seat alone and friendless and then the realisation that you have no friends hits you, hard and you just feel like crying but you can't because you're in school and the saddest realisation is knowing that none of those ******* are going to care if you leave. Anyways, I don't even know if this quote is how it is in the song but it is something like this.
