Help to lay my mum to rest ASAP

Hello and thank you for visiting this page especially with how things are in the world right now I hope u are safe and well. I am starting this as my mum Mary Pearl Campbell passed at end of September and I thought the funeral was sorted after getting a date which would have been today 13th October but it turns out that it was postponed as the funeral directors want payment before it goes ahead. I don't have all the details but all I know is my mum Cant be laid to rest because of money. Which is so upsetting. I feel like I have failed her for more than one reason and I just want to give her the send off she deserves. Any donations would go to her funeral which is £6500 at least. I don't want to keep my mum waiting any longer,bless her heart but I am working with two kids and don't have savings so I Cant afford it neither can my siblings. The funeral was scheduled for November 6th but we can't pay them and has been postponed again. I thought there could have been a payment plan or something but as far as I've heard there isn't. My sister is dealing with all the papers and officials and I feel I need to do what I can to help for mum which is reason I am here. We have applied for a grant which I belive will have to be paid back but it wont cover the full cost. I'm not 100% sure how much it is hence the large amount I am asking. I wish I wasn't here asking for money but this is for my mum. I know she always wanted a horse drawn carriage but we are struggling to give her a normal send off and its terrible. Anything left over from donations will go towards any debts she has left that wont be cleared and helping my brother who lived with and looked after her so well. A very hard year for all off us I know and after losing my dad early this year and waiting two months to lay him to rest with the covid putting the world on hold, it has been very emotional time and the grieving process is painfully held up when you can't proceed. Now my beloved mum has passed and I Cant afford to lay her to rest and I feel ashamed. I feel selfish being here asking for help but its for my mum its least I can do and I just appreciate you taking time to read this even if you Cant donate thank you for listening and I wish u all good Health and peace. I am more than happy to pay any donations back over a period of time. I don't belive I'm asking for money but this is very important to me to give her a good send off its for my mum not me. Any donations no matter how small are a big help so thank you in advance.I will donate the first hundred as its all I can spare at the moment. Thank you again. Amanda
