You can't be too far away from me if you used to go regularly to Heathrow!

Maybe you're trying to push to do something that's a huge thing - so instead of Heathrow, go and take some pictures in your garden or in a local park or woodland?
It's certainly not something to be angry with yourself over, that is a huge thing! Heathrow is huge, busy, stressful etc Too much when you're still poorly...
