I am getting destroyed every time

https://www.op.gg/summoners/euw/RyoSaeba-3333 Hi, this early season as being terrible for me, even if it started very well once i started to reach diamond 3 elo it became like a wall for me. My all time peak is master 150 lp and everytime i start to play there i feel like i cant do anything anymore, like ennemy toplaner is gonna be in my head and thinking 10 time better than me. Do you have any tips based on my op gg or in general ? Thank you
