Cabin fever
Cabin fever is generally a temporary feeling of negativity, irritability, or listlessness due to being confined to a place for long periods. Not everyone ends up getting cabin fever when immured indoors for long periods. The feelings arise because you are stuck at home, you cannot go out, and you cannot do your regular stuff. People with more introverted personalities, for example, might be better able to stay busy and entertained when they are cooped up at home. Those who are more extroverted, on the other hand, may struggle with feelings of isolation and loneliness to a greater degree.
