Brexit vote panic decision ...looking for advice

Not sue if this is the right place to post but anyway …
After Brexit vote I panicked and sent all my savings in GBP UK bank to a foreign bank 50K with a 6 % a year fixed .
Now it seems the pound is recovering and wonder should I send it back to the UK . I really need GBP not USD . I know it was a foolish move and Ive lost 5k pounds already . TSB bank are extortionate to transfer with . I have little idea about money markets but should I accept my mistake and hold out for a year hoping the pound will lose value to the dollar or get it back into a UK bank now .?
Thank you for your advice .
Its my life savings and my job is low earning so its already a massive blow to me .
Regards
