... and we suffer more from imagination than from reality. - Seneca
One of my favourite Stoic quotes.
I came to Stoicism to work on my tendency to free floating anxiety (I have a debilitating chronic disease, my wife has a worse chronic disease, she can no longer work, I'm struggling to remain employable, how will we pay the bills, etc and so on).
Through Stoic meditation and contemplation of thoughts like this one, I have gone from frequent anxiety episodes to feeling almost 'normal'.
Just thought I'd share.
