"Why are you even bothering? You have nothing new or interesting to say. What are you, a mommy blogger? That's so extra lame. Stick to your day job, you're a shitty writer. If you MUST blog or whatever, you should at least have a niche. What's your niche? Life? Single parenthood? The Internet? SOCIAL MEDIA? Your hair looks horrible and you have bags under your eyes. You're old and ugly! And a hack! And you're just looking for attention. Stop bothering. You won't succeed at this anyway."
I actually spent about three years in therapy talking - not exclusively, but a whole lot - about this asshole who lives in my head and says hateful things to me all day long. By the end of three years I had learned how to talk back to the asshole, and the asshole got a lot quieter. It turns out that the asshole in my head mostly just wants a hug and a cookie, and needs to be reminded that assholes should be quiet and sit down and let the grown ups handle things. I'm just out of practice, and the asshole has been slowly taking advantage and moving into more and more rooms in my head.
The asshole is just scared, that's all.
Have a cookie, asshole.
