Minor in comparison to losing a child (although I've suffered the loss of 3 pregnancies, one at 20 weeks) but here's mine:
Money worries - forced to retire through ill-health, it hasn't been easy since.
My health - Arthritis in my upper and lower spine/knees and FM
Loss of my mum, 12 years ago
Dad with Vascular Dementia
Coping with my kids; most have issues including ADHD, ODD, Aspergers, Dyspraxia, CVS, and OCD.
I've done a lot to counter all of the above, including medication and counselling, but most of all, cycling has helped me de-stress and clear my head to face another day
