What is the meaning of
take your mind off
To take your mind off is an idiom that means to stop thinking about or worrying about something.
[Merriam-Webster]
: stop thinking about
// This will help you take/get/keep your mind off your problems.
Interestingly, Oxford Dictionaries uses a variation of it—take a load off (someone's) mind:
Bring someone relief from anxiety.
‘providing the income you will need after you stop work can take a load off your mind’
It's possible this is a regional difference in idiom usage between Britain and North America.
The UK version reminds me more of take a load off (one's feet):
[Merriam-Webster]
chiefly US, informal
: to sit down and relax
// You look tired. Come in and take a load off.
