How to recover data from guest account in lollipop?

Hi xda guys :)
Need help if possible...
Last week 1 visited to goa and other cities with my family to spend some time...
All the pictures were taken in guest account but by mistake I clicked start again instead of confine...
And everything vanished :crying::crying:
Please help if.. If any software can help me?
Or any other solution....
Device - oneplus x

Thanks :)
