Her later years don't sound so bad to me. As an artist, I can understand all too well the need to isolate. For me, it is not just a huge part of my creative process, but a social thing as well. I love to be alone, need to be alone. I enjoy my own company. I find the presence of other people, and the demands they make on me, very stressful. This doesn't mean I am a total hermit, never associating with other humans - I do have other people in my life - but the ones who stick around are the ones who understand my need for space, my need to "recharge my batteries" in solitude. And I do have my animals. They are the best company. I know I am not the only person like this, and it's likely common for artistic types. There are periods of loneliness, but being lonely isn't always about a need for throngs of people around you...
I can't think of anything more pleasant than leaving everything behind to go and live in a small village by the sea, especially in a beautiful place like Cornwall. Sounds like heaven to me. And our friend Pamela produced her art up till the end, no? Granted, she did not have what it took to be successful financially - talent is not always enough - and this may have been a disappointment for her, but it doesn't mean she wasn't happy. After all, art is not just about making money. She had her faith, her companion, lived in one of the most beautiful places in the world....I think she may have been very content - AND, as things turn out, she did make a huge impact on the world with her art!!
