My mum (60) has been recently diagnosed with cancer and she'll be starting both chemo and radiotherapy on Feb 10th. Every February half term we travel to Slovakia for the annual family ski trip however this year my mum cannot come due to treatment. My dad has also decided to stay home to be near her Incase she experiences any harsh side effects. She wants me and my dad to go but he's staying. I (17) really enjoy this holiday as I meet up with family I don't always see, though my mum said she'd feel unsettled with me away. I would just feel guilty if I'm not there but sad if I don't go on the trip. I don't know what to do.
