<human>: Can you provide a brief rundown of the text in within 3 sentences?

My grandad is in hospital in a coma. Today they are withdrawing all but pain medication as all scans and tests show no neuro function nor reflex response. He will be gone soon, could be half an hour, could be several.

My grandad was a cantankerous man and could often be quite mean to me but I did love him and have cared for him every weekend for the last three years since my nan's death.

My mother, his daughter, and my brother are in there with him but I froze when I got to the door and can't go in.

Part of this is that I wasn't prepared for him being on a ward; grief is an exceptionally private emotion for me, one I rately even show my family or friends, much less the strangers in the beds next to him. Part of it I'm sure is denial, and a large part is the fear that seeing him brain dead and covered in tubes and pipes and wires will tarnish my memory of him.

Having said all that, I am equally scared that if I don't take this last chance to see him I'll regret it. Any advice from someone with similar experience or even just opinions woild be welcome.

Thank you.
<bot>: My grandfather has been in a coma and today doctors will be switching him off, as it were. Scared to see him and let this be my last memory, but equally scared I'll regret it if I don't.
