The missing piece

Have you ever tried to completet a puzzle (with at least a few hundred pieces) and encounter the situation that it somehow doesn't fall into place?And then in most cases discover that most probably a piece is missing, but there are so many you just do not know which one it is?
Well, I kind of have this feeling :)

Because if I list down what is in my life, you just can not find the gap on this list. I have my place, more or less stable :P, work is great, I kind of also have free time :) and I do spend it (even if I go out a bit less, so that I can go home in January), I have my friends here...etc.The first reaction, coming naturally, is that I'm just missing home and family, which I do...but this is not it.I'm not entirely sure if I would have had the same situation if I would have stayed in Hungary, but I think the answer is yes. Coz thinking through the difference of my life here and how it would be in Hungary, well, not that very significantly different.

My usual approach would be that it must be some detail, what I did not take good care about....but it does not feel like.
And now another discovery, just looking back at this very post...full of "feel" and assumptions, haha, seems like I'm slowly learning to listen to my instinct (or I might just have too much time to think, lol).

Anyways, I didn't mean to go overly philosphical. Just when people ask me how am I doing (and now I'm not talking about the daily random nicesties) I'm stuck on how to respond. Because I'm good and doing really fine - and that is true...but not full heartedly...and it is not bad, I do not mean to express I feel bad...just missing that one piece, which I have no idea what it is :D I will scream when I found the piece :)

End of "deep" post, again I managed to reinvent the wheel and shake the world with my wisdom over myself :P
