I'm neither for nor against apathy

The days have gone fast, so to say. Saturday morning I was hung over, surprise that, but things got a lot better when bf arrived in the eveining. Sunday went by with treats and movies and cuddling, no problems with that either. Monday morning I wake up as my bf gives me my cell, which also works as an alarm clock, I get up, make my coffee and fall asleep on the sofa a few times, managing not to spill my coffee though. To work I go then, not properly waking up on my way there, shrugged that off, time to start working, just too tired, sit there staring at the floor. Eventually I decide to go and see a nurse. Go in, get sick leave for that day even though haven't got fever or anything. I come home, go to sleep for 5 hours, stay awake for some 30 mins and sleep some two hours, after that bf has to go so I stay awake for him, going to bed as he leaves and I wake to take my evening meds and go to bed. This morning I woke up, drank a cup of coffee and called boss that I'm sick. Been sleeping all day. This is the first time I'm properly awake. Dunno what's causing this. I do like sleeping, but am overdoing it at the moment.
