    I am interested to know if it's nature vs nurture that has caused my issues... Thank you for researching these links and hopefully providing answers that lead to better mental health help.

    As someone who's struggled with their own mental health, I am fully supporting the GLAD Study and its ambitions to find effective treatments that are more targeted. I want to encourage as many as possible to sign up and contribute to the fantastic outcomes it will hopefully achieve for mental health developments.
