S - Socialise
Unfortunately, Dylan's depression has caused him to become socially alienated. He spends very little time with his friends and family and, as a consequence, now feels desperately lonely.
Don't socially alienate yourself!
Loneliness in itself isn't a mental health issue. However, there is a strong link between the two. Having a mental health condition often increases a person's sense of loneliness, and feeling lonely can have a negative impact on your mental health. This vicious circle can be very damaging.
For this reason, it is important that Dylan engages in some kind of social activity to maintain good mental health. He must break out of his bubble of isolation and re-connect with his friends and family.
Dylan feels like he's stuck in a bubble and unable to interact with others.
We all have different social needs, some people are content with a few close friends, while other people prefer to maintain a larger circle of acquaintances to feel socially satisfied. However, research suggests that most people cannot cope with more than one-hundred and fifty friends. This scientific curiosity is known as Dunbar's Number, and is named after the man who discovered it . The figure is broken down according to a "rule of three": Fifty of these people are considered your close friends, people you might invite to a dinner party. Then there's the so-called "circle of fifteen", people you see on a regular basis and rely on for sympathy. These are the friends that you feel comfortable confiding in about most things. Finally, there are your five best friends. These individuals comprise your close support group. (This breakdown is, of course, an approximation and the groups themselves are fluid, i.e. the people in each group may change over time.)
Although it can help with depression, Dylan shouldn't solely rely on sites like Facebook, Twitter and Instagram to satisfy all of his social needs. Engaging in conversation online might make Dylan feel less lonely, but meeting face-to-face with someone from his close support group will do him more good. This deeper connection will make him feel cared for and give him a greater sense of belonging.
Facebook is a useful way to keep in contact with friends and family, but shouldn't be over used.
Recent research  has also shown that four out of the five most popular forms of social media appear to be harming young people's mental health, leading to increased feelings of inadequacy. Services that focus on image sharing, like Instagram, are the worst offenders and appear to cause body image worries, support bullying and promote feelings of anxiety, depression and loneliness.
However, these negative effects seem to be associated with heavy use of social media. Like almost everything in life, these sites are broadly beneficial when used in moderation and can actually strengthen your mental wellbeing.
Instagram, if used too frequently, may damage your mental health.
Feeling lonely is a lot like feeling hungry. Just as your body uses hunger to tell your brain that you need food, loneliness is your body's way of telling you that you need more social contact.
