Identifying and diagnosing a mental health issue is never an easy process. Most mental health struggles do not live in isolation, and many of us have negative thought or mood tendencies that, while challenging, do not qualify as a disorder, such as depression to PTSD, just to name a few.
Human closeness is fundamental to our mental well-being; without it, any number of pathologies could plague us. The loneliness that arises from a lack of human closeness could easily bring about any number of presenting problems. If you feel that your loneliness is causing you mental health issues then share your thoughts with others going through the same or similar issues as yourself in this support group.
