Kooth and Qwell are a couple of Online Mental Wellbeing Community apps that are currently available, for free, for the public to sign up to. It’s anonymous (they only ask for your month and year of birth as each product is for certain age ranges) and you can self refer to the service whenever you want.
Their primary goal is to support patients who are in waiting lists to be seen by Primary MH Services and those who do not fill the criteria for those services, though they do also provide support (in some areas) to wider family members and loved ones. Kooth is for people aged 11-18 (up to their 19th birthday) & Qwell is for people aged 18+
