Social obligations

I am currently unemployed, handicapped, and do not have a car. I pretty much stay home all day, and attend no social gatherings. Even so, I seem to not have enough time to keep up with all of my social obligations.

Today was a Saturday, and I thought I would have quite enough time to start reading a book and to do a lot of programming. Instead, I spent the majority of my day talking to people.

• I woke up at 11AM, and was picked up by Aqeela to go to the airport. She drove on the freeway, took a wrong exit once, we got stuck in the middle of the street on a red light - it was fun. We got to the airport, ate at Starbucks, found and used the airport chapel, and came back. It was almost 3PM by then.
• When I got back, I turned on my computer, and David started talking to me. We talked about which computer he should get while he's still in Chicago.
• Then Sara Samy started talking to me. Then Nancy started talking to me about her visiting the dentist and having her wisdom teeth extracted. And then Laura too, telling me she would be online later. Sara Samy told me she wanted to video chat with me, but I told her I was expecting another video call soon, so we stopped talking.
• Then Jerol talked to me, and she wanted to video chat, so we did. For about 2 hours or more.
• Then Laura came online, and so we had the video chat we had planned the day before. We had a nice 1+ hour-long video chat, along with her family.
• Then I programmed for a little bit, but then my aunt came online and talked to me.
• I'd left a message for Echo which she hadn't responded to, but then she came online and we started talking. So we talked for about 3 hours. We just finished talking, and it is now 3:22AM.

There very well seems to be something wrong with this pattern. I barely did anything for myself today. Most of these conversations were nice, entertaining, positive, but I felt pulled from one conversation to the other, again and again, all throughout the day. How to avoid this? Should some friendships be cut? Or be kept with less frequent conversations? The convenience of instant messaging can be a little overwhelming when so many of your contacts find your conversations very likable.

UPDATE: Solution: Do not open instant messaging clients when do not want to be disturbed.
