Behavioral symptoms are useful in identifying others who might be suffering from this adjustment disorder. Signs vary widely but include social withdrawal or an unwillingness to engage in and commit to social events. Homesickness is often accompanied by speaking about home and comparing the new situation with the old, familiar surroundings. An over-eagerness to interact with people back home or speaking about plans to travel there, along with unreasonable levels of irritability, a refusal to eat and seemingly little need for sleep can occur. In a work or college context, laziness within the first few weeks can be a manifestation of the lethargy associated with homesickness.
