‘Great to be supported through a difficult time and this (MBSR) has truly been a gift that I will always have and I think not only support me, but my family and friends because I will be in a better place’
How mindfulness helped with pain, stress and anxiety
• ‘I at first wondered if the programme was for me. After the first session, I was in tears, but Caroline convinced me to continue with the body scan and I did. It has helped me greatly with my pain (peripheral neuropathy for 18 months). Other practices have helped me with daily stress and remaining calm’
• More aware now of anxious thoughts and their effects on the body. Aware of when I am reacting to thoughts in a stressed and anxious manner.
