So confused

Hello, I am new to all this and feel this is a big step for me.
I lost my mum in 2007 to breast cancer, she was only 44, then in 2011 my older brother took his own life at the age of 29.
After 25 years of marriage with my mum, my dad moved on 5 years after my mums death and married.
Since then it’s been all down hill.
Without going in to the ins and out and to cut a long story short, this week I have been told my dad is palliative with blood cancer.
My relationship with my dad had broken down due to his new wife!!
I have never had any professional help with dealing of the kids of my mother and brother and I just can’t get it out of my head the fact of losing my dad too

I do understand why you say you are ‘so confused’ because you passed is catching up with the future and have to deal with all those emotions that been kept in a box that the back of a cupboard. Don’t over think the present situation but be there if your dad needs you. We do not have an end date stamped on our forehead so enjoy what time you both have. Later perhaps think of counselling if things don’t improve. Take it slowly what ever you do. S xx
