Carolyn, 
I agree with this part of Shannon's comment: "It takes a lot of courage to put yourself in what you know will be a challenging position". And I think the same courage is the reason you are in Bulgaria....Not sure that kids environment is good for studying a language, hope you prove me wrong. 
Are there any free summer classes you could attend? At schools or universities? Or at what used to be called "4itali6te", if they still exist?
