That is very hard. I know I visited in another country for two weeks and the differences were subtle like you describe, just not expected! I have asthma and don't know what I'd do if I could not sleep with the thermostat down so I was cool, etc. I know what you're complaining of. Any way you can call around and find an air conditioned gym or some other way to exercise in a cooler space?

I keep carrots and celery around, eat the celery with peanut butter (or cut up an apple and "dip" it in the peanut butter), etc. when things are tough. Not much fixing? I would have just told your boyfriend, "okay, thanks for the reminder" and done whatever I thought was best for me and gotten back to your discussion about your father and how you miss him. I don't know that I'd want to talk to someone that insensitive though, even if they were just about all I had? Do you journal at all? I'd start a journal, try to make it funny, listing all the annoying little ways things are different daily?

Don't know what you can do with the non-reliability of some people. I'd wait for them 10 minutes then call them and do something else if they don't answer or aren't responsive. I'd try to hang around more with groups of people so at least someone might show when plans are made?
