How do you come back to casual after cedh

I've almost only been playing cedh for more than a year and now when I come back to casual I can't wrap my head around plays ppl make. Every casual player to me now seem bad or dumb.

For example the other day I got mana screwd for like 6-7 turns that I did nothing. Someone casted a chord of calling x=7 and I countered bouncing an Island with daze. And suddenly I became the threat bc I casted one free spell when everyone had a well developed board.

Other times has happened that someone is clearly going for a win I try to stop them and someone else reprieve my counterspell bc they don't like counters????

Anyway. How do you de al with this frustration with casuals. I also play 60cards format for the competition but cedh has a especial place and it's becoming hard to come by in-person games around where I live.

Edit: What I'm asking is how you flip the switch from cedh to edh and still enjoy yourselves.
