We will not know unless we begin.
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.
No pain that we suffer, no trial that we experience is wasted. It ministers to the development of such qualities as patience, faith, fortitude and humility. All that we suffer and all that we endure, especially when we endure it patiently, builds up our characters, purifies our hearts, expands our souls, and makes us more tender and charitable, more worthy to be called the children of God... and it is through sorrow and suffering, toil and tribulation, that we gain the education that we come here to acquire and which will make us more like our Father and Mother in heaven.
