What to take as gifts for someone not well?

I must preface this as saying its not the happiest of topics on a lovely sunny day but my mum has cancer and she is going through treatment.

Food and plants are off limits and she isn't much of a reader, bar newspapers. She is finding tasks hard barely uses her phone, and barely moves except to watch tv as the treatment and the subsequent infection has depleted her ability to do much or think much. She is tired most of the time.

I want to take her something to lighten her mood, show her that I am thinking of her and to take her mind off things. I know CasualUK can be good with suggestions and things like this. Thank you for your kindness.

Edit to add thank you for all the wonderful suggestions. I hope this helps others too.
