I always think there are two me's - summer me, and winter me. Summer I might not be healthy, but I will usually have some times that I don't even have to think will I have energy, be ill, etc; wintertime, I will
be tired, ill, depressed, rundown. And it is the sunshine - if we have a miserable summer, I go into wintertime mode.
The moral of the story is don't live in Northern Scotland.
Maybe I should go somewhere sunny - I hear Seattle is good ?
