I know how you feel... yesterday I went to sleep 1am and woke up at 6am when my cat jumped on me, so obviously I was really tired and got back to sleep at 9am... woke up again at 3pm which already sums 11 hours, that would be fine if I wasn't so tired at 5pm... Then I forced myself to watch some movies and the World Cup game just to stay awake.
Now it's 1:30am and I reached my limit, going back to sleep... also because if I stay awake any longer I'll start to get the real drepressing thoughts. so, see you later
