I think that grumpiness was part learning to handle chaos, and part feeling really isolated. Yes, i like my privacy, but when you're in a new country and you have no one who you can trust, it can lead to a lot of heightened emotions.
Today though, i noticed that my moods have evened out somewhat. I attribute it to being used to what's around me and what to expect, having a nice group of friends i can trust and rely on when i need it, and also, eating a mostly whole-foods diet. True, we tend to grace the outdoor tables at the local Italian pizzeria at least once a week, but beyond that, our diets don't include very many processed foods. Fruit is abundant and i've figured out what vegetables i can get on a regular basis. We eat these delectable Costa Rican cookies that are often stocked at the local grocery store, but that's kind of my one indulgence. OK, and beer. But for the most part, we don't have access to pre-packaged sauces, loads of dairy, or indulgent desserts.
As far as isolation goes, i believe i now have just enough support to feel like i have a safety net, but not so many friends that i never get anything done or have time to work on my plan for the future. In short, our deprivation and isolation are sometimes good things.
So sometimes what you see as stress-inducing at first is actually leading to something good... to growth and health and all those good things.
Speaking of support, i love what Support for Stepdads is doing to support blended families and the strong men who step up to parent other people's children. Hear hear!
