I'm sorry that you're struggling. I think venting and seeking support/advice about this is a step in the right direction. Waiting for surgery is a right pain esp with it being so far out. I wish there was more I could offer.
In case anyone's curious, I tried soloing with Glaceon (full EV SpATK , 2-way split BT HP & DEF, Snowscape, Calm Mind, Ice Beam, sand attack, and holding Shell Bell)
Turn 0 - Breaking swipe (lower attack of all pokemon)
I almost succeeded in soloing but got one shotted by fire fang towards the end. I found that odd, BC usually the game prioritizes super effective moves earlier in battle. My Glaceon got hit by 90% of the raid by Earthquake.
My wife and I are both neurodivergent and she frequently does this. I learned to be direct and have her give me the short version because I don't have the patience or the attention span to hear the long version.
So long, and thanks for all the fish! o7
