Hello, Its 4:18am And I've Been Trying To Sleep For

Hello, its 4:18am and i've been trying to sleep for about an hour now, i've had a cold for about a week now along with a blocked and runny nose. Im so tired i jusy want to sleep but i cant, my nose is really blocked i cant seem to unblock it, i cant breathe out of my nose what so ever and its really uncomfortable! I've tried literally everything.. I've tried Vick Vapo Rub, lifted my pillows up so im not competely laying flat down, i've blown my nose, put a hot water bottle on my forehead and filled a bowl up with hot water from the kettle and breathed in the steam but non of them have actually helped.. Any ideas?? I need to be up in 5hours, im so knackered :( just want it to go away.
