I'm 25f living and working overseas alone in my dream country. I have a well-paying job, a fun group of friends, and a handsome and very loving boyfriend. So why do I feel so broken?

For the past month I've been feeling so down. I don't want to do any of the things I used to like. I don't go out with my friends, I don't paint, I don't watch shows anymore. I've called in sick to work so many times because I would get anxiety and just break down. This has never happened to me before. I've had problems and been sad in the past but never like this where it's physically hindered me from doing anything. I look at my life and know that I should be happier than ever, which makes the fact that I'm not even worse. 

I don't know that I'm asking for advice or confirmation or anything at all. I think I just wanted to write this all down. If anybody gives insight or so, it could help and will be appreciated.
