Why would someone say this to me on snap?

I was simply posting on my Snapchat story and this girl replied saying the exact words, “you post so fucking much on your story I guarantee nobody cares at all and I swear everybody swipes right through it Jesus Christ you’re annoying.” And then blocked me. I don’t even know this girl. It truly made me upset because I already have no self-esteem so this only made me feel worse about myself. But I was only posting about my favourite singer coming out with new music. I don't know why someone would say that.
