Dropped from almost p3 to gold 4...need advice!!

Hi all! i need some advice about ranked.. I really dont know how but i dropped so fast lately i'm trying everything and everyrole to find a carry solution but nothing seems to work :( I'm usually a player that punishes misplaying or misspositioning...I went into p4 with relatively ease as support, but after enchanters nerf i dropped like a bird hit by a thunder (not implying this nerfs being the cause of My drop, i just take that period as a checkpoint). After keeping to play support and trying always to be positive i got i couldn't carry anymore...could not be impactful anymore even doing good D; My Friends told me to become An assassin or burster cos It would fit better with My playstyle, should i try for It? Since plat is far Now...should i do some experiments? I'm really really confused atm!
