Learn Swiss german

Hi there! I am Swiss (dad from Bern) but grew up on a French speaking region and my dad didn’t want to speak Bärndutsch to me (he preferred speaking a broken French). I still feel that a part of my soul is not complete since half of my family is Swiss German. I really wanna learn it and thought about Migros club classes, does anyone have recommendations? Also i don’t speak German (i picked Italian in school, i know i should learn German but i feel like it’s gonna take sooo much time to learn both languages). Anyway, thanks xx
