There's the flaw in your argument. There AREN'T any other nations in the same boat as us.
Norway and Switzerland are net exporters to the EU; we are net importers FROM the EU.
We contribute 12.5% (gross) of the entire budget of the EU. When you factor in EU spending in each member state in order to identify the biggest net contributors, the percentage we contribute GROWS. Only Germany pays in more (net) than we do.
Financially the EU as an organisation is dependent on us to such a degree that it may well not be able to continue existing if we leave. Additionally, large numbers of large European corporations make a large chunk of their profits in the UK. Therefore we hold a far stronger negotiation position than Norway or Switzerland did when they negotiated their terms - the EU won't be pushing for anything, they'll actually be giving us an awful lot of what we ask for.
As the eurozone economy continues to stagnate, the proportion of British trade accounted for by the rest of the EU is falling, and non-European markets are becoming more important for British exporters. But this is not a reason for the UK to leave the EU.
Membership of the EU significantly increases Britain’s trade with other member-states, while there is little evidence that it reduces trade with countries outside the Union. Britain is home to a larger stock of EU and US foreign direct investment (FDI) than any other EU economy and is the preferred location for investment from other leading markets. Some of this investment would be threatened by a UK exit from the EU.
If Britain were to leave the EU, it would face a difficult dilemma: having to negotiate access to the EU’s single market in exchange for continued adherence to its rules – or losing access in return for regulatory sovereignty that would be largely illusory.
As for the last part, you're living in a fantasy land if you think the EU will bend over for Britain after this. Absolutely no chance - the consequence of leaving has to be severe to send the message to others, and under the rules they dictate fully the rules for leaving.

All I continue to see from people who voted Leave is a completely imaginary scenario with zero chance of becoming reality.
