I just shared my own experience, which I would call bitterness. Basically, I couldn't appreciate the good parts because I was blinded by the bad parts. Maybe there's a better word than bitter, I don't know. I won't assume our situations were identical, so feel free to disregard what I said if it doesn't apply to you...
Then I'm curious, what country would be ideal for you to live in? And have you lived there as an adult? In my experience, you only get a true sense of a country if you live there as a working adult, even better if you have kids. As a student, or short term visitor, there's no way of knowing what it's like. That's why my image of Sweden was so rosy (and also because I didn't know anything else), I hadn't actually lived there as a working adult by the time I moved back. Likewise, my view of the US took a sharp turn for the worse once I entered work life there.
This is a sideline, but I want to be very clear: I don't hangout with expats (I'd say 90% of my friends are Swedes), and I have no illusions whatsoever about the faults of my original country (the UK), which I would never move back to. As a person who grew up in England with parents from Spain who were Basques, I'm actually very critical of 'patriotic' sentiments, and extremely aware of the personal biases that they involve.
I'm definitely not bitter - but I'd say it's typical of you as a Swede to characterize my hatred of Sweden in that negative way.
