help with funeral cost

I recently lost my fiance to cancer he was diagnoed in oct-nov 2015 with terminal cancer, was was given 4-12 month and sadly he lost his battle on 16.2.16. We was due to make funeral arrangements etc.... On 17.2.16. Robs funeral was held on 26.2.16, the dwp paid a majority of the funeral im left with £689 to pay and i just cant see how i can pay it off as im not getting alot of money myself. But i really want this paid off, so im asking from the bottom of my heart that if people can donate £1 and share with friends and they donate £1 then hopefully i can get this paid off for rob. Please please can u help.
