'All happy families are alike; each unhappy family is unhappy in its own way.'- Leo Tolstoy "Anna Karenina"

That quote came to mind reading your OP. Oh how, I relate in my own way. I'm certainly in a period of grieving, ergo some situational depression ergo a strong desire to remove myself from those not in my inner circle(pc in its way is an inner circle as I write and write and write it out most days, eh)...but there's this a deep sense of disconnect from society in a way. There's a certain unpleasantness, that in times like this I have such distaste for. It's when I prefer the solace of my home, books to withdraw myself.

It's not in a way of worrying/comparison. Think what they want, they'll think that anyways, I say, in regards to your OP. They'll carry on in their own worlds, own troubles, own woes, own dysfunctions-believe me, there's a lot more of that in this world than you'd be led to believe. What's that saying? Those that mind, don't matter and those that matter, don't mind?
