I feel like such a fool.. a guy messaged me when I was online?

saying he was an Army General, and I was chatting to him every morning online.. this went on for weeks.. then he said he was leaving the army and he wanted to buy property and would I help him look., so of course I said yes.. because I wanted to help him.. then I found properties in Scotland for him (which is what he insisted on), then I drove a total of about 700 miles to look at these properties.. he said yes, he trusted me and would send the money to purchase them.. it was over 3 million pounds, plus he said he would add my expenses/fuel/Hotel Etc.. the trip cost me hundreds.. Then he said he was wanting me to go and live in Scotland, look after the house I`d chosen, so I quit my job to go there.. I then gets a phone call at 5.a.m. supposedly from the airport, some guy saying he was a diplomat for the Army, saying he was trying to get through customs with the money but needed 750 quid to get through because if I paid the money, he wouldnt need to get the luggage checked.. I didnt give anything over but I feel such a twit.. what a scam.. plus lost my job.. just be careful, people...
