Om Swami
Why does being alone make my depression and negative thoughts worse?
Isolation feeds depression
We have a tendency to think negative and depressing thoughts. Isolation makes you depressed, and a depressed mind seeks solace in isolation even though the person doesn't want it.
One of the first and classic signs of a depressed person is the inability to connect socially. They want to have fun, to enjoy, to go out and do things, but the mind doesn't let them.
