I feel like a bad mom!

Fellow mama's, do you ever have a day where you are mentally off? Where you just can't shake that feeling and it's for no apparent reason? It's hard to explain, but you wake up just feeling "blah".

I woke up like this and for the rest of the day I couldn't shake off the feeling of just not feeling like myself.

I feel awful because I feel when I'm in that mind set, I'm not the best mom. And by that I mean, not the chipper, happy go lucky mom I am most days.

I'm nursing my son before bed and just feel horrible, as if I gave him a bad day.

Anyone else have those days?
