For a month or so, my emotional life was going down the day. Every day bleaker and more paranoid than the next. It peaked when I sent a cryptic goodbye message to my a friend, saying goodbye. I did not reply to their IRL greetings. Now, once I'm feeling better, I miss them and wish to resume the friendship. But.. they didn't try to ask me what was going on, why I did what I did, and so on. And that's keeping me in check. Maybe they see me leaving as a relief, maybe they "know" to stay back, maybe they're just not mature enough to talk about other emotions than irritation and enjoyment. Any advice on how I should do this, IF I should do this?
