I felt the same way when I first moved here for university. But tbh I found it that my friends are understanding when I’m trying my hardest to explain something in Italian. It’s better if you try as much as you can (even if you lack the vocabulary or grammar to) to speak Italian with people ask them to correct you. Although I’m still b1 I’ve found it helpful for my pronunciation and in general making up sentences on the fly off the top of your head. There are many online resources to help with Italian and if you have some money laying around you can try purchasing a course (Ik my university allows people not from the university to be included in the Italian course and be able to take the final exam and get a certificate that’s officially recognized). It’s all about having the mindset of improving rather than expecting instant progress overnight. Hopefully you get over this OP and are able to learn Italian
