Does anyone else ever get days where they have little to no energy? I felt like this all day today, and I just feel like my muscles don't want to work right and that it's a huge task just to get up to walk to the bathroom. I don't know if it's coming from depression (I have bipolar) or if I'm coming down with something physical. But wow, I am feeling so lethargic... body does not want to move. And getting winded easily.
