Man... i already did awake in the middle of a lovely dream, like you... and i understand perfectly how it feels... its really a heavy coming down... i never did use hard drugs, but can imagine how it may feel like... its sad, sometimes even dispairing...
Well... unfortunately i havent any good advice for you... just a quote... excuse me if it may sound a bit harsh for your situation, but its true:

"Women is much alike bus. Instead running behind one, just wait the next one."
