The Stages of Being Alone (in my experience)

1. Excitement: I can do whatever I want!
2. Boredom: What the heck should I do?
3. Loneliness: I just wanna go somewhere or do something with someone…ANYONE!! GAH!!
4. The Click Cycle: Endless time spent clicking almost at random on the internet or scrolling through your newsfeed on Facebook. If someone asks you later what you did online, you don't even remember.
5. Resolve: you start to use your free alone time as an asset. Now you can read whatever book, watch whatever series, or learn about whatever things you want on wikipedia without being interrupted and actually make a lot of progress. At this stage you're probably being productive about unimportant things like TV shows, though.
6. Productivity: you take your resolve and time and start using it to better yourself in some way. You cultivate a hobby and make it a skill. You add to your resumé; you do helpful research related to your chosen field of study/future career. You create and become creative. You write meaningful letters to people, rather than wallowing in self-pity and talking yourself out of several desperate sounding messages.
7. Logical loneliness: You've been productive for a while; you've learned how to make this whole, "Being Alone" thing work for you. But now you realize that you need companionship on a fundamental level as a human being. More creativity, and perhaps, randomness and talking to yourself, ensues. You also become more proactive about calling friends on the phone.
8. You finally have a chance to hang out with people again…and the cycle is reset.
