Mental health problems are the largest source of global economic burden (regardless of this) because mental health problems are very often linked to other health problems. However, changing the way the public views mental health can make it easier for people facing these problems to ask for help. Organizations working to change perceptions of mental health in London include Think to Change, Together for Mental Wellbeing and the Mental Health Foundation. The organization called Richmond Borough Mind, associated with Think to Change, has a wellness center about a mile away from the Richmond University campus that offers volunteer opportunities. Volunteers are able to run activity groups, such as drama and creative writing, as well as work in the office, help with community fundraising and provide advice. Most importantly, volunteers provide companionship to people with mental health issues, which is essential because mental illness can be an incredibly isolating experience..
