Sleeping Beauty

Yesterday I stayed in bed all day, I only got out when my partner arrived home just before 5pm. What the hell is wrong with me? I have had many days recently where I just can’t get myself out of bed out of sheer exhaustion for no particular reason at all. Today however, I was up before 7am as I had my voluntary job to go to. I’m not tired or sluggish today so I have no idea what’s going on, maybe the exercise tired me out? Going to make the effort to get out of bed early every day as it’s just too easy to fall into its trap!
