I assume the last line of your post is your comment and not the German source. You are so desperate to be right on your predictions you are now using words like apocalypse.Senior German sources were apparently saying tonight that they value the integrity of the rest of the EU block way more than a potential loss of (some) trade with the UK. If that pans out, then that's the "apocalypse" scenario right there.
What you are like is the spouse of the abused partner who is so shocked at the spouse leaving that they are sending messages scaring them by telling them how hard life will be , but the abused spouse will reply that it's a price worth paying to be outside the abusive relationship.
You will be right on some things, people accepted when they voted to leave that there would be a short term shock and even possible hardship, but they considered that a price worth paying.
