I went through the exact same thing when I was living in Spain and learning Spanish.
I didn’t feel that I fitted in properly. It was a feeling that I really hated!
After one dreadful party where I felt excluded from every conversation, enough was enough.
I took my learning into my own hands.
I focussed on learning slang; the colloquial, informal language that native speakers use in everyday conversations.
It changed my life! It changed my conversations!
But most importantly - it was SUCH a fun experience!
