Honey, I have spent all the money I

Honey, I have spent all the money I came with here on Goods, Shipping and hotel here and on our flights tickets to Thailand and its a Serious issue, because I just called my Bank in England to ask them where I can use my Credit Cards here in Africa, they said I can't use my Credit Cards in 16 Africa countries due to their poor Banking system here in Africa. I was shocked and now i am really confused. I don't really know what to do now and I have a lot on my Credit Cards.
