Post breakup relaxation trip recommendations?

I posted this in the SFT subreddit. I copy/pasted my OG post, but I also included some info at the bottom.

Found out my ex was cheating on me, a lot, in my car. About 2 weeks later my landlord told me they’re selling the house and I have 30 days to get out.

I desperately need a relaxing, turn your brain off, just existing kind of trip.

I’m looking to go ideally in January/February timeframe. Anywhere outside the US so I can feel as far from that asshole as possible. I’m a Black woman, racism is everywhere, but I’d like to not go to places more known for it. I’m not opposed to cold weather (if there are hot spring spas or something), but I vastly prefer warm weather.

My budget is around USD $5000 including flights. Favorite major airport willing to travel to is LAX

I’m [more than] open to the other side of the globe, as it stands I’ve been outside the US to a few South American countries, I lived in Hawaii for a couple years, I’ve taken 2 Caribbean cruises. This will be my very first time solo traveling though!

Sorry if this isn’t very helpful, but any suggestions are very appreciated!

ETA: Thinking my trip will be a minimum of 1 week, maybe longer if I can find a place where USD goes far. For me, turn my brain off relaxing is just about anything in or by the water. It doesn’t have to be the ocean - springs, lakes, arroyos, rivers, streams, fjords, bayous, hell I’ll take a puddle if it’s deep enough to cover my shins during sunrise lol.

I’m not opposed to central/South America, but I realized I’d rather go somewhere out of the realm of things I’ve done before? Idk if that makes sense? Ignore me if not lol.

I’d like a walkable place if possible? I’d like to walk around and sightsee my food options.
