One of the hardest things about being in Fandom Mourning: Inventing excuses to people in RL as to why you’re so upset.
You can’t just tell your boss that the reason you’ve been on the verge of tears all week is because your favourite show is ending.
You can’t just tell your coworker “I’m sorry I snapped at you. I’m stressed because I’m waiting to hear if this show is getting renewed. I’m sure you understand.”
No. You can’t even talk about your real feelings. You have to dig down deep, find some other issue in your life that’s causing you minute distress, and use that as an excuse for your behaviour.
