@Sara First off, welcome to Bulgaria! I've found learning Bulgarian challenging. I've took an intensive course at ИЧС in Sofia when I first moved to Sofia. Today, I'm taking private lessons at my high school ACS and I got really lucky to find a tutor through my blog in Sofia. Are you in Veliko Turnovo? I'd ask at the university--you might be able to find a student at the university who would be willing to tutor you.
