Hi seashell
I too am new here
And as a dad with cancer, I can see the pain it causes others.
I have a few small tips that I hope can help you through the journey with him.
1) We all have a cuddle meter , the thing inside us that measures how much we are loved by others.
It is a vessel that can be filled and can be drained
To fill it up is easy , saying I love you and better still giving them a cuddle to pass the love to them . The bonus is it works both ways, the giver and the receiver get their cuddle meters filled up.
Sadness and illness drain the cuddle meter very quickly and if its empty to long then depression and other negative states occur.
So be happy around him and give him lots of cuddles , not as easy as it sounds under the circumstances.
2) The emotional shock waves that are generated by such events are very strong and like the NZ earth quake they have many after shocks, you need to learn how to feel an emotional after shock as it comes on , through simple breathing techniques control them so that they are not overwhelming. By slowing your breathing down , and focusing on the breathing, you will bring your heart rate down and slow the rate the emotional chemicals are traveling around your body. These emotional chemicals are needed for us to deal with very dangerous situations but can also make us unbalanced if we get to much, like anything else.
I hope this is of some help.
