Losing my mum.

Hello. I'm new to this forum. And, I'm new to cancer. 
My mum has been unwell for some time and losing weight. She is in her 80s. We had a doctor to come and visit and he has confirmed that he is 95% certain she has cancer and the best thing we can do is help with pain relief. 
 

I am posting on here because I have no clue how to manage our emotions. I took her some flowers today, and I just can't help thinking of what she must be going through. 
 

it's just a matter of time really. She has no weight on her. 
 

I hope some others that are going through this or have been through this can share their coping mechanisms.
