My experience has been the same as yours, lil. Back in March I just came back to my country from almost 3 years abroad, and I had plans to go out and do many things with my friends. When the recommended quarantine started, all those plans were put on hold indefinitely. I got to see my friends once or twice in the two weeks we had before quarantine, but that's it. During the pandemic, I have the exact same "online messaging" experience you have. I rarely get messages, but when I do I usually postpone answering them. Maybe because I know there's no way that those people are asking me for something urgent, after all, we can't leave home to do anything anyways. I almost never send messages or reach out to friends, but I think that's because of depression/anxiety/low self-steem, that got worse during the quarantine. Although, I already told some friends not to expect to hear from me, and they seemed fine with it. For now, I keep interactions with my close family (those who live in my house) and girlfriend.
