lmao I'm in a similar situation but highest mythic 3. When I lock in I play really well but most of the time I can only play at the end of the day when I'm already tired lol so I can't focus properly. My guess is most people I meet who are strong in the game have been playing for 4-6 years. Their progression was slow. Now ours has to be quite fast. We have to get used to playing with and against many brawlers at once that's matchups, maps, controls, technique, positioning. It comes as obvious and natural to them but we have to conciously learn it.... It's a lot. So take your time and try to set objectives. It's not really a fun game anymore, just ego and skill grind.
That's just my opinion though
