Thank you PCG

1-Gong to US does not mean you have to convert from being British to some thing else.
2-Ticket back to UK is like 200$..why would you regret---unless you come on a ship which sails away after dropping you off.
3-You may lose aabyea--and still dress very modest--there is always room for change.
Be open.

I say go to US, and experience life. Don't think to much over it.
