I cant figure out that I'm getting bad at the game or my opponents are just too strong

I recently peaked asc 2 and Im playing for exactly 1 year and valorant is my first fps game I have 0 past fps experience. so the the thing is when I got to asc 2 on my own I was dominating mid-thigh asc lobbies easily but suddenly I was unable to play at all I tried taking a break I tried using a aim routine but I just can't play at all like I used to play just a month ago? from asc 2 I got deranked to plat 3 and and Im still struggling in P3-D2 I cant even get to D3 now. someone please help me with this I'm getting so sad seeing my gameplay getting worse and worse day by day
