(cannot speak to the culture shock / heartache for an international homesickness, but) when i moved to seattle from nj / nyc metro the stark constrast between east coast / west coast also really got me down – what worked for me was finding other transplants in seattle and commiserating, finding restaurants that served cuisine that reminded me of home and befriending the staff, and going to nightlife events that played jersey club, or booked djs i knew had their ear to the streets and were playing artists like cash cobain, chow lee, etc. that were coming up in new york as i was missing them by being away from home
if those spaces don't exist, putting in the effort to start them and do outreach to find other people who feel similarly to you is going to be so valuable! if you can find just one other person in your situation and foster community with them by immersing yourselves in the culture you miss whether through potlucks or listening parties, eventually two will become three will become four will become more
(since you mention you're from / missing brazil specifically – i'm still here is doing a ton of "for your consideration" screenings rn, and baile funk is having a moment in the general zeitgeist at global sound events at least where i'm at so i'd imagine elsewhere as well potentially... i think it's hard if you're in the midwest or suburbia where those kinds of events are less available but if there's something out there i'd check for those things specifically to find people who, if not in the exact same situation will have an appreciation for the culture you're missing and can fill some gaps, if not the whole thing)
