Mom wants to move back to mexico?

This is a bit of a strange situation but I (22F) wanted to see if I could get some guidance or advice to navigate this situation. Hopefully this is the right subreddit for this (also i’m on mobile sorry for the formatting)

My mom moved to the US from GDL, Mexico about 20 years ago for marriage. She’s not happy in the states, since she’s been my brothers full time caretaker. She never really had an opportunity to fully assimilate and expresses that she feels very lonely out here. She wants to move back with my brother (19M) (potentially my dad as well but that’s very up in the air right now for a few reasons) All her friends and family are in Mexico. Our extended family is very financially stable out there. They’d likely start off with staying with family.

Thing is, my brother is disabled. He’d have to transfer over years of medical records. I’m thinking of going with her for the first year of her move to help her get back on her feet and find a place and a job and some general support (or staying in the states and working and sending her money… idk!). My brother and I are in the process of getting our dual citizenship right now.

Does anyone have any experience of moving back to Mexico in a context similar to this? Experience with living with disabilities in Mexico? Finding a job after having grown up in the states? Transitioning into a life here? College? Anything I’d need to know to be able to pass on to her? Finding places to rent? idk!!

Any forums that I can check out as well would help

I really don’t know where to start and just want to see if I can gather any other insight and experiences similar to this outside of friends and family! Sorry if this is super broad lol, it feels pretty overwhelming right now. anything helps big or small thanks!
