Funeral/headstone and extra costs

My name is Katie Jackson and I am one of Tracey Jacksons children. We recently learnt of my mum passing away nearly a month ago. Unfortunately due to our financial and family circumstances we are unable to provide her with anything to properly say goodbye. I am estranged to my mum and have been since the age of 8 years old. My other siblings are also estranged. I am the next point of contact for her and if anyone can help to donate to costs then I will forever be grateful. I'm at university so have no funds. With the council arranging the burial this will help to put mum to rest finally. However I wish to purchase a headstone for her as her grave will be unmarked and I don't want that for her. Also any other raising will go towards a celebration of her life in her local in which i wish to put on for her other family members and friends, also flowers and anything extra will go towards this.  *Edit - the money is now to cover the burial as the council will no longer fund this and any extra will go towards headstone in time*. Thank you x
