An explanation for my current emotional state

Acclimatization is the process of an organism adjusting to chronic change in its environment, often involving temperature, moisture, food, often relating to seasonal climate changes. (In laboratory conditions, this process is controlled to one variable change only and is termed acclimation). Acclimatization usually occurs in a short time, and within one organism's lifetime (compare adaptation). This may be a discrete occurrence or may instead represent part of a periodic cycle, such as a mammal shedding heavy winter fur in favor of a lighter summer coat. Where acclimatization occurs naturally, some authors have used acclimation to describe the process of an organism being forced to adjust to changes in their environment by artificial means, such as in a laboratory setting.^[1]
