Kind of feeling lonely playing league

Since my friend introduced me to league last year I have been binge playing this game the entire year. Since my brother's death and my parents' divorce, I have been seeking escapism in league with my friends. Haven't done anything good since I was living by myself inside my apartment. All I do is watching animes, playing league, occasionally go outside for a swim and sleeping lol. Right now I'm finally back on track and am about to become a college student but still I can't get the feeling like I used to when I was a NEET. I don't really find league interesting anymore perhaps its the repetitiveness. I haven't play with friends since then because I lost most of them since I quitted league some months ago in order to boost my grades and earn some dollars at Starbucks. Now I just feel lonely when im playing league alone by myself :( How could people truly enjoy this game without friends? I saw bunch of people at my school were playing solo ranked but still enjoying the game and I dunno why. Sadly I can no longer find league enjoyable but for some reasons I still intend to play ...
