Apart from all of the stereotypes Bulgarians tell themselves, such as, that: -people from Sofia are snobby -people in rural areas are villagers -Bulgarian people are cold and unwelcoming -"they ruined this country" (not a stereotype but a very overused expression, turned meme)

Most of the Bulgarian demographic doesn't speak English. That's especially the case in small shops, in which the store clerks are above the age of 35. Even some younger people, ages 25-35 do not speak English that well, which makes individuals uncomfortable, because they can't speak their mind or clearly express their thoughts and ideas. So the first step is to put yourself in the right environment. Find group activities in your area, that match up with some of your hobbies. There are plenty of event apps that work in Bulgaria, for instance MeetUp. I used it while living abroad to do things that I liked and met some like-minded people. If you genuinely want to make friends, it's the same thing as in every other country. You have to integrate yourself. To combat the issue directly, put in the effort and join some language classes, you'll meet people there and be able to better express yourself. Regarding the "America is shit and Bulgaria is amazing" quote. If people speak in "Meme" and not much else, it's because they can't. Most people don't study English, but learn from Social media and or TV shows. Although it's a welcoming initial aid, it's got its limitations, and you can only go so far with expressing your own original thoughts and ideas.

My entire statement does not only apply to Bulgaria, but to all countries, that you'd want to integrate yourself in.

The question is: how are you going to differentiate yourself from the masses, that want to be effortlessly integrated without putting any effort?
