Thanks guys for your good wishes yesterday - it really helped! The interview was weird and I have no idea how well it went but I should find out if they want me to travel there for a second interview at the end of the week. The second interviews are not actually happening until the beginning of November though so even if they want me it's not exactly a fast paced recruitment process.
Yesterday I had a real struggle not to binge over the whole situation and today I've been hungry all day - but still haven't binged. Yesterday I trained and my plan is to do so again tomorrow.
