Polarbear - Sorry to hear of your sad loss. I truly sympathise with you as I too lost my mother through cancer 24 years ago and it is like yesterday.
I have also lost 2 nephews through tragedies so I know the deep ache in your heart but as they say time heals.
You only have one mother
Patient, kind and true
No other friend in all the world
Will be as true to you.
Remember although she is gone she is looking down on you and helping you.
Hope your brother feels better soon.
God bless!! XXXX
