I started getting these attacks in 2009 just as my music career was taking off. I'd be doing photo-shoots and started to feel like I was having heart attacks. Increasingly I found it difficult to step outside my flat. Things started to get better after I saw a therapist who told me I needed to make peace with my panic attacks.
I can't believe it's been four years now and from watching that pilot we really all looked like babies. It's unbelievable just how far everything has come. I'm happier now than I've ever been on the show and in my life. I really owe so much of my happiness to 'Glee.'
