How do i control my saltyness and how do i keep my cool?

First of all, i know you want to say ''Just mute them'' but that way i can't speak with them, witch lead to defeat in most results. Plus i can get reported for refusing to communicate. So if you guys had any ideas cause my personality is complete crap. Like last game we had 2 guys that gone off afk... i was Salty cause we were winning and it was ranked my promos.
