This sounds like it is a difficult time for your father and hard for you to see him so unsettled. I feel this is a prime example of how the mind and the body are so intimately entwined. When thoughts embed themselves, creating irrational thought processes, creating a feeling of being stuck in a rut. Have you heard about Bioenergy Healing - the treatment re-connects the energy pathways, releasing memory patterns along the way and allows the person to move forward with clarity and focus.Bioenergy Healing uses unique hands-on/off  and scanning techniques that can access your body's Biofield to release memory patterns that governs every thought, feeling, physical and physiological function and action. This approach causes a rewiring of your brain and body, rather like pressing master reset buttons. 

A series of Bioenergy Healing treatments enable each piece of your life's jigsaw to start slotting into place bringing with it - clarity, focus, confidence, positivity, self-esteem, ability to adapt, coping mechanisms and increased energy levels. www.bioenergyhealing.org.uk
