I'm from the UK and voted out and I'm not regretting my decision, we knew there would be some fallout and that was expected, but the FTSE 100 and 250 are back to where they were pre-referendum and the pound has been on the incline slightly.
I don't think we'll go into recession, the 2 year window for negotiation with the EU is going allow us to negotiate some trade deals with these countries and others we previously couldn't due to EU law. Only if we really fuck up trade negotiations do I see us risking a recession.
The (older) Brits are used to weathering hard times it kind of defines us to some degree, and there's a lot of scared baby liberal teens who feel entitled to the world who are worried but generally speaking we'll get our head down, work hard, make the deals we need to and move on. I don't see this as a big deal at all, certainly not worth the cost of losing our sovereignty.
As a display of how much leverage England has in negotiations, ponder for a while why the EU is telling them to leave quickly while they waffle, and EU refusing to hold informal talks while meeting with Scotland. If the act of your leaving is now more desired by the other side of the table, it doesn't bode well for your position.
