yes we are all sick of it, but what follows will be a far stronger United Kingdom. Of that I have no doubt.
You are looking backwards imagining that we are still ruling over an empire. Those days are long gone but have left a bad after taste for the countries we once exploited.
Have you looked at China, India et al? They are taking over large parts of the world's economy and trade, their global power has been growing but we are too arrogant to take note and adapt to the changes.
We are, as a single country, now largely insignificant as is the US. As part of the EU we have some power left, especially if we lead and steer, rather than moaning and acting like obstinate toddlers. Even the EU is growing weaker in comparison with e.g. China but we have some negotiation power as a EU member and a large group of allies with relatively shared interests and relatively share cultural contexts.
Get behind the bloody country and stop bloody moaning.
If you want to be patriotic you would do your support the UK being part of a supportive and strengthening union not isolate us and support a corrupt and incompetent government.
The EU is not a perfect system but as we still have to trade with them we will have to abide by their rules anyhow, our national negotiation position is so much weaker than the EU's. If we don't trade with the EU it will be us suffering not them so much.
How can the British government expect to get special allowances from the EU if other member states don't get them as well? That doesn't make sense and is childish and entitled. Also the UK actively shaped these rules so it's not something that is "being done to us".
I'd say we're better in than out. We always had the option to regulate EU immigration if that's a sore point but our government chose not to use these options, blame them not the EU.
On a side note, do people realise that the UK is bankrupt? It's not talked about but do have a little read here www.cobdencentre.org/2010/08/the-uk-is-broke/
As ever, turkeys voting for Christmas is the best way to describe Brexit.
