4am in the morning and I can't sleep (Panic Attack)

I have to work tomorrow AND a really important conference call at 10am but I can't seem to go to bed. There is just so much to do!!! Oh my god oh my god oh my god.... Project potentially delayed??? cost overrun??!?!? *panic panic panic*

I ALSO haven't finished studying for my 2 LOMA papers in November and my Japanese paper in December.....*more panic more panic more panic*

AND THEN..............................
Person A: "Psstttttttttt, ok, I think the panic attacks are gone. You can come out now..."*looking around furtively*

Person J looks out from the corner of the building, crouching low, eyes bloodshot and wild with worry. "Are you sssssurreeeee? What about Mr big bad tomorrow?? Will the panic attacks return with him....................?"

Note: A day in the life of a STRESSED OUT working-class habitually nocturnal creature. It is very tough....trust me.
