4. Isolation
Many symptoms of depression are silent, progressive, and very difficult to detect unless you pay a lot of attention, which is increasingly difficult for us nowadays due to our racing lifestyles and our mental overload. Perhaps one of the most subtle manifestations of a depressive state is progressive isolation.
Even though people with bipolar disorder who are currently cursing a manic episode could be hyper-social and talkative, depressive episodes have the complete opposite behavioral manifestation. People who are depressed become more and more isolated for a number of reasons.
They feel tired, lack the motivation to go out and reach for people, and are so full of self-doubt and self-loathing that often believe they are an annoyance and nobody loves them. As a result, they become more and more isolated, which makes it more difficult for them to get help. Extreme isolation also raises the risk of suicide.
