Develop awareness for mental health issue Prevention and intervention are two different actions with each of them needs assessment which one is more effective to be implemented depends on many things. Spreading awareness is an example of prevention while hypnotherapy, or drugs treatment is an example of intervention. People usually talk about severe mental illness which need to be diagnosed professionally not just self-diagnosis to 'label' ourselves or other people with mental state condition we can find on DSM. That severe condition needs intervention (or treatment, in clinical term). That is tough. Before mental healthy people become mentally disorders and if it is untreated then become chronic and therefor leads to severe mental illness, we can do something in the first place. To prevent the issue becomes larger and heavier. Yes by building and developing our awareness about the symptoms or signs. No need psychoanalysing or deep thinking, the signs are mostly observable. Michelle Obama wrote an article and mentioned about Five Signs people can recognise that there is mental health issue going on in a person: Agitation, Withdrawal, Hopelesness, A Decline in Personal Care, and A Change in Personality. We can start from these aspects to practice our awareness if we seriously concerned about mental health. Maybe the first person we can observe is ourselves.
