do u play any instruments?

& how did u start playing it?
i have a violin but ive just had no improvement on the instrument at all, and im apart of a string club full of guitarists whereas im the only violinist. i really wanna know how to get good at this. it pains me knowing that people can play beautiful melodies with the same strings that i struggle to even struck a proper chord with. and yes i know all about the chords, finger practices, and things u have to maintain in order to play it. i trim my nails weekly, have a supply of strings & rosin but recently ive hit a slump and i went back to square 1 how do i fix this??
