Hi im sorry about your mum. I can only speak from the point of view of having had cancer. The practical support was what i appreciated the most and i would say dont offer just do, i would say its fine if asked but some people just turned up a did stuff which i really appreciated. Also if your dad does open up dont try to make it better as such, i didnt open up much and when i did people would try and make it better by saying i was being stupid as such, i knew some of my thoughts and feelings were stupid but they were my thoughts and i suppose i just wanted someone to listen and validate. I hope this makes sense i know what im trying to say but not the best at putting that into words. Sending hugs. Xx
