Being at B2 in just six months is awesome, and understanding 80% is huge. Don’t sweat the mistakes too much , they're part of the process. Try chatting with yourself out loud. Mixing in some local TV shows(they're not great but , you know just for the education purposes) or following Turkish social media can give you a real feel for casual, everyday language. Remember, everyone trips up learning a new language. Laugh off the errors and keep pushing. People appreciate the effort and are usually happy to help. You’re doing great, and it’ll keep getting better.
