The process of adaptation to a new situation in the conditions of the disease is treated as a new, difficult adaptation. In this context, special attention should be paid to mental disorders, in which the feeling of losing control over one's life, state of mind, vision of uncertain future, can be a significant obstacle demotivating the individual to take up the effort of struggling with the illness, which would consequently be very helpful in regaining health.
