Do I miss being abroad?

Spend the last 4 days abroad, back in the country and city where I lived for 4 years. I was really sad as I missed it so much...
I now feel like I am not living, as if people I used to go out with are living it out much more, experiencing more, getting stretched more.
And I am annoyed at work. Annoyed at people, no time for them. I miss the old job a lot. I was travelling, which I loved and I was working with people from differente nationalities which was great.
