Many people asked me, then kept asking me, if I was okay. I responded in "mhrrmm"s and "ehh"s.
Then they said they were sorry.
Please don't tell me you're sorry. I don't know what to do with someone who is apologizing to me, especially for something they have/had absolutely no control over. Apologizing for apologizing will do nothing but make me angry with you.
If you absolutely MUST know how I'm doing, talk to me for about thirty-two seconds. If I respond in monosyllables or facial expressions, or not at all, it means I am probably in a dismal mood and do not wish to speak with you. I do not hate you, in fact odds are I like you. Possibly a lot. I just don't want to have a conversation with you at the moment. Try again the next day. If my mood is merely antisocial, I will tell you as much and then scoot far, far away from you. If I respond in a positive manner (i.e., actual words that don't include the phrase: "I'm not in a very social mood right now"), talk away about anything you damned well please. I'll offer commentary when/if I see fit.
I tend to be more relaxed about this online. I feel rude closing a chat window unless the other person has been silent for at least twenty minutes (I often chat with very easily distracted people who will sometimes forget they were talking to me and will vanish for a bit every now and then). but again, the monosyllable rule generally applies. If you're not getting more than one or two words out of me, odds are I don't really want to chat, and I'm pondering signing off and returning on a screen name no one knows, or just logging off entirely.
Trust me, if I see fit for you to know, I will let you know how I am doing.
*sigh* as always, exceptions to this are Michael and... probably Tish, most of the time. Though I hate sympathy from anyone, I will do nothing but twitch a bit and possibly seethe quietly if they offer it.
