Haven't RTFT...but feel this is the perfect place to tell my tale of shame from yesterday....
In London....HAD to cross that horrible footbridge (Millenium Bridge?) over the river.
I have a pathetic fear of heights, I mean just stupid.
I nearly had a full blown panic attack on the escalator in the NHM.
It's especially bad on bridges with open type railings, in my old town there was a footbridge across a dual carriageway, and it made me feel sick and v dizzy everytime I had to use it.
Anyway...in order to get across the bridge yesterday, I had to take my glasses off, put my scarf over my head, and do a sort of half jog thing across. Firmly in the middle, not looking at anything, hard breathing, with one eye poking out of my scarf.
Barging through everyone taking a photo like an escaped bull.
Must have looked like a complete and utter loon.
So to anyone who saw a complete weirdo scuttling across a bridge in central London yesterday, looking like a complete freak...that was me. 
Also sorry if I ruined your selfies!
I know it's irrational, I literally can't help it.
