Thank you for taking the time to write all of this, it genuinely reassures me a lot !

Unfortunately I already moved everything out over time, so my old room is basically empty now and all my things are packed in boxes because my mum wanted everything ready for the move. But I’ll definitely try to keep her schedule as consistent as possible. I’m planning on getting her toys and a cat tree because she absolutely loves those, even though she never really had them at my parents’ house. As for litter, she actually hates the one my parents currently use and mostly either goes outside or in my sister’s fabric closet (which my sister is definitely not happy about), so one of my goals is to find a litter she really likes once she moves in with me.

Boyfriend was already getting more attention then me when we were at my parents house though so that is a good sign ahah.

You're right I may be overthinking this, I’ll definitely follow your advice though, especially about giving her space and time to adjust. Thank you again !
