Part of the reason you might stop doing things you enjoy is that you feel very tired. Depression often comes with a lack of energy and an overwhelming feeling of fatigue, which can be among the most debilitating symptoms of depression. This could lead to excessive sleeping.
Depression is also linked with insomnia, as one might lead to the other and vice versa. They can also make each other worse. The lack of quality, restful sleep can also lead to anxiety.
