A Cardiff-based research project is looking for 6,000 people to share their experiences of living with mental health problems.
The National Centre for Mental Health has already spoken with 1,800 volunteers - some of whom have mental health problems and some who do not.
The centre said huge advances in research would not be made unless projects like this were taking place.
