Emigrating to the US you need, as a Brit, to have a skill the country needs, or close relatives already there, or win a 'green card' in the annual "lottery", or enter under the E-2 system by buying a business which you will manage. All fraught with stress, with no % certainty of success in any method.
Emigrating anywhere, I'd suggest you take an extended holiday, to see if it's what you really want. After a few months you will know if living surrounded by foreign, [ no offence intended, dear chaps! ], methods, lingo, food and lifestyle still attracts.
Best of luck, anyway.
Dnk: No, you do!
