Tired but awake

It's 4:13 am and I'm still wide awake but so exhausted at the same time. I'm pretty upset but that usually doesn't stop me from sleeping.. just doesn't give me a good dream.. I don't understand why this is happening but lately I never sleep until 3 in the morning and today I'm still awake! I wish my boyfriend was up at this time but sadly I'm all alone tonight and obviously since it's so late but still.

I feel like just staying up all night now since I'm already awake and just sleep when he gets up for work :(
