I can't anymore for some reason

Ever since I beat my current hardest Out of Mind (26/8/2025), I couldn't beat a single level after. I seem to have developed a habit of playing levels, getting them in 3 - 2 runs then seemingly get bored of them and barely play them again after switching to a new level. I also noticed that I started mainly look for levels with easy endings (I have a problem with nerve control) which seemingly started after I barely could do Acu's ending.

For reference: "Acu" 85% , In 2 runs "Hypersonic" 46% , In 3 runs "Niwa" 23% & 52% - 100% , In ? runs "In Circles" 40% , In 4-5 runs "Supersonic" 35ish% , In 4 runs "MikuMikuMikuMiku" 52% , In 3 runs "Hallucinate" 40ish% , In 3 runs "Future Funk" 72%, In 2 runs to 99% And finally "Seeker" 57% , In 2 runs

In which Acu, Hypersonic, Niwa and In Circles (The hardest in between these & around heartbeat difficulty) are extremes, Future Funk is the only hard demon (picked it up to train my nerve control) while the rest are Insane demons

I'm still trying to beat my first extreme Mobile 60hz (With CBF)

I'm ball and duals carried, okay at rest of the gamemodes and very good at learny gp.
