Good news, scammed53,
you are not in trouble at all if you do the following:
Just go to your local police tomorrow, show them the printed email correspondence and tell them all you know.
Have a look at the parcels: Who sent them? Call the store or company and tell them that you have been scammed, that you suspect the parcels have been paid for with stolen credit card details, and that you want to return them.
Then you should be fine.
The scammer will not be happy
so don't read his mails, enter him into your spam filter, block him on chat, and don't accept his phone calls. You have had enough trouble and don't need to be threatened by a scammer.
Of course, he can't do you any physical harm - he won't leave his internet café in Ghana.
