Your garden helped to heal you. there is a lot of research that supports this fact, heres a snippet from WA state,
Horticulture Therapy
A systematic review of over 240 scientific studies found reliable evidence to support horticultural therapy as an intervention for a variety of conditions, from cerebral palsy to schizophrenia.20 In one study patients with chronic musculoskeletal pain who participated in a 4-week horticultural therapy program experienced an increase in mental and physical health, as well as an improved ability to cope with chronic pain.21
After just one horticultural therapy session, patients recovering from cardiac surgery experienced marked improvement in their mood, and stress reduction.22 Beyond treating acute health conditions, research shows that horticultural therapy can also benefit individuals trying to overcome emotional or physical trauma. In one study adults with diagnosed depression participated in a therapeutic horticulture program and showed significant beneficial change in mental health aspects of anxiety, mood, and depression.23
