This is not too difficult for you! If this seems impossible to even start practicing just begin by playing the first three notes on the E-string. Sit down and watch your favorite YouTube videos as you play these three notes over and over again. Relax your hand as you do it even though it can seem hard. Decide to do this every day for at least 30 minutes and by the end of the week this is actually pretty easy. then add the note on the B-string.
