Helena's health was not robust, and she was addicted to the drugs opium and laudanum. However, the Queen did not believe that Helena was really ill, accusing her of hypochondria encouraged by an indulgent husband. Queen Victoria wrote to her daughter the Crown Princess of Prussia, complaining that Helena was inclined to "coddle herself (and Christian too) and to give way in everything that the great object of her doctors and nurse is to rouse her and make her think less of herself and of her confinement". Not all of her health scares were brought on by hypochondria; in 1869, she had to cancel her trip to Balmoral Castle when she became ill at the railway station. In 1870, she was suffering from severe rheumatism and problems with her joints. In July 1871, she suffered from congestion in her lungs, an illness severe enough to appear in the Court Circular, which announced that her illness caused "much anxiety to members of the royal family". In 1873, she was forced to recuperate in France as a result of illness, and in the 1880s she travelled to Germany to see an oculist.
