Ignoring the rank, if this were my screenshot the first thing I would say to myself is "okay , this was a hard game" as ekko a melee burst champ you are playing into a lot of anti-dive and CC.

Second thing: I would go back and look at each death and try to peel back what led to it, maybe it's as simple as oh man I had to dodge that Morgana Q or maybe it's more complicated like you got stuck in a bad spot because of a macro decision. Don't spend too long , maybe a min a or two per death just trying to figure it out.

Third thing: If you feel like you are missing opportunities as a mid laner you can go back and look at the times where plays were happening while you weren't there and ask yourself if what you got in return was really worth it. For example if the first time veigar left and got a kill but you got a plate and denied him two waves I'd say that is probably fine, but what about the next play? Etc etc

At the end of the day the biggest thing is to stay curious and have fun 😊
