Depression has certain criteria, for example things like you don't enjoy anything, you feel tired all the time, you consider that you shouldn't live, and so on. I had a mild depression, and I know this is not it. I am happy, I like to meet people from time to time, etc.

It's not addiction either - I spend my days on the Internet (or in computer games) a lot, but if I had to spend a week without it, it wouldn't be a problem. I don't have to be connected 24x7 either. I also sometimes abandon the game for no reason.

It's really just you don't feel so motivated by the things in the real world compared to virtual possibilities. Let me reiterate, I think parent was spot on when he talked about the "artificial Skinner box of instant rewards", and I don't think there is a psychiatric category describing this.

It's not a mental disorder, just like overeating (and being overweight due to that) isn't (usually) a disorder. But yeah, it may be a mental health issue. It's mentally unhealthy behavior, just like eating too much is unhealthy.
