anxiety
"WOW  I've just come home after delivering my big presentation to over 100 people. It was incredible. No panic, no shaking voice, no crazy beating heart, just calm....
I'm blown away.. normally I can't even talk to over 3 people. Didn't realise how much social anxiety had limited my life until trying this medication- I feel like I can finally be me.  
Sadly It was only prescribed as a one off from my GP to help with this event, she said I'll need to try counselling in future."
