I'm moving to Mexico from the US. I will be bringing with me a ton of allergies that give me asthma attacks. Wish I could leave them behind. Where do folks recommend to live? I have always done best on the coast, possibly in the desert (desert may be better as I do badly in humidity), but I need to be in a good-size expat community as my language learning is poor, it will take me upwards of a year to be competent. Also I need good healthcare services. Any advice very welcome, thank you!
