How do i enjoy even the worst of games of League of legends and how do you play solo

This feeling comes and goes but never really leaves. When i try to find a match of even blind pick pvp normals which is like the most casual type of lol there is. I used to not be able to play this game at all because this feeling. But for a while the game was kind of enjoyeble when i played with my friends. But now that feeling even comes when i try to play with them to. I think I get this shity feeling because of the feeling of helplessnes when all lanes and jungle are feeding and you cant really take on every single fed player in the enemy team alone when behind while needing to defend all lanes. I think this causes my brain to just treat it like a danger of some sorts. And its not easy to get into the game when every few times i actually try to play it most of the times doesent feel like a good and fair lost. Say of 100 games 3 are played alone and when i play the games it often ends badly with a lost and alot of toxicity. I rarly loose hard in lane which makes me feel helpless and that im wasting time.

I was wondering how you the potential reader enjoy playing the game solo and how you cope with the feeling of wasted time because you cant do anything other than loose fast or slowly with a bad team.

Thanks for any kind replys and thoughts on the topic.
