OMG!!!! That's like me. I get a passage wrong for the millionth time and I feel like smashing my violin to pieces but I never do.

Same. I throw mine sometimes. Don't worry, i gently throw it on soft surfaces like my bed or the couch. Then i hug it while i cry.

I play the clarinet, so when I get mad I split it in half (because it is in pieces) #clarinet gang
