Please answer the following question: The answer to the question: What is the first name of the person who refused to wash his hair or cut his nails during particularly bleak periods? is inside the article: In the months following Pink Moon's release, Drake became increasingly asocial and distant. He returned to live at his parents' home in Tanworth-in-Arden, and while he resented the regression, he accepted that his illness made it necessary. "I don't like it at home," he told his mother, "but I can't bear it anywhere else." His return was often difficult for his family; Gabrielle said, "good days in my parents' home were good days for Nick, and bad days were bad days for Nick. And that was what their life revolved around, really."Drake lived a frugal existence; his only income was a £20-a-week retainer he received from Island Records (equivalent to £238 in 2018). At one point he could not afford a new pair of shoes. He would disappear for days, sometimes arriving unannounced at friends' houses, uncommunicative and withdrawn. Robert Kirby described a typical visit: "He would arrive and not talk, sit down, listen to music, have a smoke, have a drink, sleep there the night, and two or three days later he wasn't there, he'd be gone. And three months later he'd be back." Nick's supervision partner at Cambridge, John Venning, saw him on a tube train in London and felt he was seriously depressed: "There was something about him which suggested that he would have looked straight through me and not registered me at all. So I turned around."John Martyn (who in 1973 wrote the title song of his album Solid Air about Drake) described Drake in this period as the most withdrawn person he had ever met. He would borrow his mother's car and drive for hours without purpose, until he ran out of petrol and had to ring his parents to ask to be collected. Friends recalled the extent to which his appearance had changed. During particularly bleak periods, he refused to wash his hair or cut his nails. Early in 1972, Drake had a nervous breakdown, and was hospitalized for five weeks. He was initially believed to suffer from major depression, although his former therapist suggested he was suffering from schizophrenia. His health problems..., can you guess it ?
