Pop star Adele finds it difficult to live in Britain due to a mental health disorder which affects two million people in the UK.
The NHS has since informed us with a list of possible symptoms.
The former Londoner jumped ship in 2016 to move to California, where she now lives with her husband Rich Paul in a mansion worth a reported $58 million (£46m).

And it seems that the Tottenham-born singer has no intentions of returning to her British roots, despite 'really missing' home life.
The 35-year-old still gets 'very emotional' when she sticks on her hit song 'Hometown Glory'.
"I really miss London, but I miss the London from before all of this happened in my life," Adele told The Hollywood Reporter.
The mum-of-one recalled: "I wrote it the day after I went to my first ever protest. In London, the UK, we were annoyed at Tony Blair because he was going to war with Iraq.

"It was like a million-people turnout in London, and we're marching, and I was 16, and me and my friend Olivia went. We made our placard, and it felt so powerful."
Adele then revealed that she suffers from 'really bad seasonal depression', which is why she can't come back.
She is one of 'around two million people in the UK' who have Seasonal Affective Disorder (SAD), defined as 'a type of depression that you experience during particular seasons or times of year'.

"Depression is a low mood that lasts for a long time, and affects your everyday life," according to mental health charity, Mind.
"If you have SAD, you'll experience depression during some seasons in particular, or because of certain types of weather or temperature. You can experience it in winter or summer."
The NHS has provided a list of possible symptoms of SAD, which can include:
Advert
-a persistent low mood
-a loss of pleasure or interest in normal everyday activities
-irritability
-feelings of despair, guilt and worthlessness

-feeling lethargic (lacking in energy) and sleepy during the day
-sleeping for longer than normal and finding it hard to get up in the morning
-craving carbohydrates and gaining weight
-difficulty concentrating
-decreased sex drive
The main treatments for SAD are:
-lifestyle measures – including getting as much natural sunlight as possible, exercising regularly and managing your stress levels
-light therapy – where a special lamp called a light box is used to simulate exposure to sunlight
-talking therapies – such as cognitive behavioural therapy (CBT) or counselling
-antidepressant medicine – such as selective serotonin reuptake inhibitors (SSRIs)
