This time of year can be stressful and within our distress we can be hard on ourselves and others. You are not alone, you are not an island or a rock - it is okay to feel but we must accept responsibility for our feelings and what we do with them. Reach out and ask for help if you need it - don't be afraid - just ask for help.
The buy, buy, buy constant barrage is hard to handle - try making something or being creative. I'm giving my brothers and their families a scrapbook, some glitter, a gluepen and coloured pencils - the scrapbook is entitled "Our happy holiday memories". That is a $20, 5 person present that everyone can get into. Grandparents can write and draw pictures - the kids can stick things in there and record their impressions of the days with help from mum and dad - shells, sand, sticks and leaves can be added. I am imagining that in 20 years the scrapbook can be reopened and the memories will rekindle.
The big challenge I find is to just allow the season to flow. There is no point fighting it - it is a waste of energy. Much better to flow with it and use it to further our aims - to grow communities - to bring people together - to be kind to ourselves and others. Rest and relax - swim and walk - smile and laugh. Connect with the beauty of nature and the other inhabitants of our world - admire the majesty of papatuanuku, the glory of mother earth. Recharge and energise for the challenges to come. And love, always love.
