Welcome @Loo,
You'll have plenty of time to wear your big girl pants. I think the majority of us lost the plot at the start and several times along the way, I know I sure did.
Shellshocked, yes, devastated, yes and plenty of pissed off in there as well. That's why we call it the roller coaster. One miinute your like "yep, I got this thing" and the next it's cloudy fog of doom.
People handle things differently so whatever gets you through is the right way for you. There really is no "right" way to handle this thing. Excellent that you have had a good result and that the public system is treating you well.
Best of luck lovely
