@Ohdostopwafflinggeremy Thank you, the first time will be the hardest but it feels the right thing now.
@ANiceLittleHouseByTheSeaWithACatCalledBrenda Yes, it's beginning to feel like it might actually help me with the next step now.
@NoviceVillager Oh yes, that bit about change and new opportunities.
Thanks all, going to look at flights today. The thought of travelling by myself, maybe actually looking at the Duty Free for once, having a sneaky drink or coffee whilst waiting in 'Departures', reading a book on the plane in peace, rather than going through Special Assistance and all it entails, having to be hypervigilant for hours on end to avoid mid travel meltdowns, is not an entirely unpleasant thought...
