Yes, though I lost it when I moved back with my parents. I didn't recognise it until they confronted me with it. They had moved to a place where I knew no one, and my mind wasn't in a place where meeting anyone would ever happen. My solution, though I am not recommending it, was that one day I packed a bag and headed to somewhere where I might meet up with people I knew. I had no accomodation but I did meet some old friends and I slept that night in two armchairs pushed together. I never lived with my parents again.

I think the moral might be that we all need other physical people to relate to. Sadly today actually being with people is too easy to avoid.
