Meal at the BKK airport an “extortionate”£13:50ish. Coffee and tuna sarnie at Birmingham New Street station £10:50!

Practice doing smaller activities alone before embarking on a big solo trip. Go out to eat on your own and take some solo day/weekend trips. I found this helped me get comfortable with doing things alone, so that by the time I started traveling abroad by myself, I wasn't worried.

Eating Solo: Try restaurants with communal tables, eat at the bar, or practice solo dining before you go.

Embrace Flexibility: Don't over-schedule; things go wrong, so have backups and enjoy the detours.

Check the expiration date on ALL passports. Make a note in your calendar to renew at least 6 months before they expire. Remember the two clear pages rule for most countries too!
