Nobody care about you really, and why would we?
You had the best deal in EU already, constantly whining about while getting great economic benefit from your membership and at some point you decided you were wealthie enough to rise the drawbridge, your politicians publicly shunned upon EU citizens living in UK, you kept saying you had the upper hand in negotiations and were finally free to sign any deal you wanted worldwide, and now you're begging for a free trade deal, why would we give it to you your way?
That said I hope you'll do well once you're out
