Sometimes we just cant be there, I wasnt with my Dad either when he died, I was 'too tired' after work, it took me a while to forgive myself.
His last words were 'dont worry if you cant be here, I know you love me and I love you.' He died later that week.
Time is a healer. Its hard when roles are reversed and you become the carer/ parent- how lucky your mum is to have daughters who love her so much.
I shall be thinking of you all. Take care . Valxxxx
