Lost Lace has broken me

Sad to say this is the first game I am going to walk away from on account of difficulty (I think I am starting to get old and my reflexes are slowing). Simply put, I have beat the whole rest of the game with moderate effort (60ish hours), have 95% completion (all needle upgrades and all but the last mask), and I now have 10 hours into Lost Lace and still only have a 25% rate of getting to stage 3 of the fight. I am pretty sure with enough time I could get there and blast her with tools to close out (but for all i know there is a stage 4 and or then I have to sequentially fight the queen again or something)... anyhow, I guess I just am not having fun with this fight. With last judge or trobio I felt progress and patterns, with lost lace, it just feels like a lot of rng that she doesn't do some bullshit that dings me (specifically the mechanics of her counters and teleportation are frustrating me). I get it is the last boss in the game but, ya, just feels like quite a jump from literally any other boss, and not in fun ways. Definitely loved most of the game, so I am sad to end on this note.
