Not stress about everything

I guess I’m farther from this goal that I had previously assumed. I had just posted on another goal and for no particular reason, a boy decided to reply harshly. There is no obvious reason for him to do so, I hadn’t done anything wrong. It hurt and I began to stress about what he had said. I was being optimistic for once in my life and he shot it down. Thankfully after a few minutes of thinking about it, it doesn’t really matter. There is nothing wrong with what I did or even how I responded to him. I still wish I had been able to brush it off for it was his fault for being unnecessarily unkind and judgmental.
