How Do You Recover From a Loss Streak...

I'm Silver 4 right now. I've been Silver2 the last 2 seasons, never put in/demoted to Bronze.

I was Silver 3. I got demoted earlier today.

I then proceeded to go on a 7 game loss streak.

I'm now down to 5 lp in Silver 4.

I've never been on a loss streak this bad. On op.gg it says I have a Bronze 1 MMR, I've never dipped that low.

I'm just wondering what the hell happened to put me on the worst loss streak I've seen in my life. It's not me being bad and 'going to where I belong', I've been steadily climbing and I got myself to Silver 3 from Silver 5. Now I've just fallen down so fast I'm about to be back where I started in the span of 1 night.

How do I even turn a streak like this around, I feel like I'm just going to keep losing more. All the progress I've made has been thrown away and I was doing (for the most part) really well. It's like my team does well, and then late game comes, and then people start slowly making stupid choices that end in a throw even if I'm trying to get us organized and calling out mias and pings and trying to get us to focus. Nothing I do is ever enough.

I don't want this to sound like a QQ thread but I'm just really....really...frustrated...I've been playing as well as I can and every game something happens and no matter how well we do the game always ends up lost. It took me a while to get up to Silver 3 and in 1 night it's all gone. I've never been on a loss streak this bad and I don't know how to stop it.
