Stranded in Spain

This is the most horrible thing ever. I overslept and missed my flight to London and now I am stuck in Seville, a city I am not fond of (though I love Spanish beaches), and I don´t know how to get home and I think that the only flights I can afford leave so late and it means I have to buy also another ticket from London to MalmÖ and I really don´t want to pay that and it puts such a huge dent in me and it cost me about $300 (US) to come to Spain and I am so, so, so mad at myself and upset that I missed my flight and I just don´t know what to do. This is so horrible and I am never coming back to Spain ever unless I have to.
