Why am I struggling so much to win games?

I went 0/10 in placements, I currently hold a 38% win rate across solo/duo ranked queue in silver. Last year I got to gold so easily and was not struggling and just getting completely ground down mentally like I am this year. What the hell changed? What am I missing? I shouldn't be getting worked up so much over this but it just doesn't seem fair. I'm not an amazing player but I sure as hell don't deserve as low a win rate as I have now. You can look at my op.gg if you desire and comment on my games. I, in fact, welcome it because I have never in my life struggled as much to succeed as I am this season in this video game. I am consistently getting 7 game loss streaks, 11 game loss streaks. I am looking at myself critically to figure out what the hell I am doing wrong and trying to improve but I have never encountered a barrier this difficult without any show of improvement to make it worth it.

Why the hell do I keep playing? Someone please help me.
