How to not get tilted after loss streaks?

Been playing luke for a month or two in casuals and the hub and not to long ago went on a 50 loss streak (not exaggerating). Obviously i was salty, but i won a game or two after the loss streak. I lost alot of games because i felt like i couldnt end on a loss but i did unfortunately. I was probabbly losing more than i shouldve because of a bad mental. How do i not get as salty after losing a bunch?
