I'm slowly reading a book by Carol Deppe called The Resilient Gardener. The long short of it is that she discusses gardening with challenges.
I think this is a valuable read because most garden books address what to do, but not really from the viewpoint of gardening with health problems, financial problems, erratic weather, etc. It's funny, but a lot of people I know stop gardening when life presents challenges. They see gardening as a hobby. When life throws them a lemon, they don't drink that cold lemonade in the garden. Plus, the grocery store is pretty convenient. Maybe folks lack the time, lack money, or get frustrated because of a physical barrier (back, knees, you get the point). As I read this book however, I think that hard times are a great time to embrace gardening- not run away.
I'm gardening in hard times right now. I am the sole caretaker of a cancer patient. Gardening gives me a break from all the emotional, spiritual, and physical hardships I am going through. Gardening helps me experience life bursting forth in contrast to experiencing so much illness and death each week at the hospital. I am also making less money because I work less, but gardening is going to provide organic vegetables that I might not otherwise afford myself. In short, gardening for me is not just about relying more on myself, unplugging from the "grid", or getting in touch with nature. Gardening for me is a necessary part of life- in good times and bad. I hope it is for you too.
