To brighten the mood

I chose these yellow Petunias at the garden centre today as my yoga teacher says yellow brightens the mood and revitalises.  Just what I need.  As those following my journal will know, I haven't been posting blips for a few weeks.  I've stopped the pain medication I was on for my sciatica as the side effects were very bad and the tablets weren't numbing the pain.  I'm still in pain, but so much more clear headed!
