the evidence is really piling up

Homesickness is the distress or impairment caused by an actual or anticipated separation from the specific home environment or attachment objects. Feelings of longing are often accompanied by anxiety and depression. These symptoms may range from mild to severe. Homesickness frequently occurs when one travels and may be exacerbated by unfamiliar environments or foreign cultural contexts.

Symptoms in homesickness may be emotional, cognitive, or physical. In extreme cases, physical health problems accompany the hallmark symptom of homesickness, which is preoccupying thoughts of home. Most people describe homesickness as a want or longing to be back home, continuously missing their parents, spouse, relatives, friends, mates and aspects of their familiar environments. People may describe their feelings as a deep sadness, depression, frustration, anger, or hopelessness.
