As someone who personally suffers from Anxiety, I am going to try to stream for 34 hours straight to raise money for Anxiety UK. Anxiety UK works to relieve and support those living with anxiety disorders by providing information, support and understanding via an extensive range of services and works regularly with external agencies and healthcare professionals to improve the service provision offered to those living with anxiety disorders. It also campaigns to raise awareness of anxiety disorders. Any support to help the charity is greatly appreciated. Thank you - Sean (Elyyt)
