Why am I not enjoying LoL anymore ?

Hey guys,
I've been playing league since season 6 (i beganthe day Jhin was released).
I've since played 1400 games in total, i have playedall roles, different champs, with friends or alone.

For ranked games I've played only my promos in S6 was placed in Silver 4.
Season 7 : i was placed Bronze 3 and climbed my way to silver 4 again playing Tank/CC junglers in about 40 games.
In the preseason and becausei was not enjoying jungling anymorei switched to mid and i enjoyed myself very much.

This season i played some ranked games ans was placed B2 but I don't have the passion to play anymore, now I only play when my friends invites me and even then i'm not enjoying myself anymore !
What do you think i should do ? Keep playing LoL or not ?
