I did a study on homesickness in my masters program. It wasn’t an extensive study, but most of the literature agrees that homesickness can occur at any time and in anyone, even if you’ve lived away from home before, for a long time, etc…
As others have mentioned, the very fact that you are away from home while raising your child (is this a first child?), without any of the “usual” support one would expect from family and friends, could be causing it. As could the fact that it has been 3 years since you were last home. I’d be curious to know if this is the first time you’ve gone that long without going home.
My advice is very similar to the rest. Try to find someone you trust to take your child for a half day or day. Find a course or activity that you like to do and do it – a class, going out with friends, joining the movie club group on here and venturing out with them when they see a flick, etc…
Also, I think the idea of planning your next trip back home is a good idea. If you have a definite time in mind when you’ll next see your family and friends, even if that is another year from now, I think it will help. I know, for me, having an end in site (especially when I am in a situation where I may not be completely happy, for whatever reason) helps make things easier.
Finally, and this may sound harsh, stop thinking of wherever you are from as home. I know this is a hard one to do. But, if your child and your husband are here in Taiwan, than this is your home. They say that “home is where the heart is.” So, where is your heart?
Ok… before you beat me up for this one… let me explain my reasoning. Peruse through some of my posts and you will know I’ve had a hard time adjusting to living in Taiwan (for many reasons which I won’t go into now). However, one thing that has started to help me, lately, is to stop thinking of the US as my home. When I talk about going to the US, I try to say just that “go to the US” or “go to back to the US” and not, “go home.”
So, for instance, in July I plan on going to the US to visit my friends and family there. But, I am not going home. I am home, right now. Taiwan, whether I like it or not, whether I’m having a good day or a bad day, is now my home. My bf is my “heart” and he is here. So, if “home is where the heart is,” my home is here, where he is.
In psychology, there is a theory that behaviors change attitudes and attitudes change behaviors. In this case, you are changing a behavior – ie., the way you think about and talk about your country of origin and Taiwan. If you can start to change those behaviors, you may just start changing the way you feel.
You’ve said that you’ve always felt comfortable here (or anywhere you’ve lived). So, if you are comfortable here, why do you not think of this as home?
Just my NT$2 worth.
