So is that why i get tilted so easily ?

Do i get tilted so easily and never see a hope in a match cause 90% of matchs is decide so early ? Is it because that i'm used to the fact that i win like 80% of my matchs cause i had early lead or that 80% of my loses cause enemy had early lead?

Do i get all blind and lose hope in my team even when there is a little light at the end of tunnel that i can't see anymore cause i used to fast early win or lose ?
