I have an old car and the other day it officially broke down for good. My mom has been texting me and calling me telling me what I need to do and bossing me around. It's incredibly annoying and I feel bad but I don't need to be bossed around right now while I'm stressing over how we're going to be able to even go to the store and get stuff we need.
