Funeral for my father

Hi all! I’m trying this as a last resort for help.
on Christmas Day I lost my dad, he sadly passed away from a cardiac arrest and other complications and the doctors done all they could but he wouldn’t wake up. I’m absolutely heartbroken I’ve lost my dad words can’t describe how I’m feeling with all these mixed emotions losing him, we had our ups and downs but he was still my dad and I loved him with all my heart.
I’m trying this as with dealing with losing my dad im left with arrangements for the funeral as im only child, my mum and dad are divorced and unfortunately my dad had no money left behind, my mum has done all she can but she only works part time and because I work full time I’m not eligible to have any help to pay for the funeral. The only thing dwp can do is give him a simple funeral which is where no one is invited to the funeral and it’s just a burial which is something I don’t want for my father as he deserves better than that.
Unfortunately it’s not something I have ever saved up for and now left struggling to find the money to pay for my fathers funeral, the only money I have pays for the deposit for the funeral and need to find another £3000 to pay the rest.

this is something I’ve never done and never thought I would have to but anything right now would help just so I can bury him and let him be at rest.

thank you for taking your time to read this and what ever anyone gives I am more than greatful.
