Duncans Funeral Service And Burial Costs

I'm currently trying to raise money for my father duncan Macdonalds funeral costs he passed away towards the end of december and I'm a 24year old man left on my own to deal with this funding wise and I have no idea where to start.Duncan was already fighting before his ops batteling PTSD and being on antidepressants and fighting anxiety. Duncan had been very unwell the last year having a aortic valve replacement and coronary artery bypass leading to having a pacemaker fitted after which he managed to get through all of this last year. Despite having further problems including frequent bouts of angina and suffering from hypertension and ontop of that led him to suffer with peripheral vascular disease and atrial fibrillation. He then unfortunately had a stroke in August which he became very unwell for but fantastic hospital teams helped him along, he managed to get home after and we thought he was on the mend. Unfortunately he got taken into hospital at the end of December with him not feeling well. after tests at the hospital they found out he had an infected blood clot where they had done the artery bypass. This infection ended up travelling to duncans brain leading to swelling and unfortunately 20 hours after being admitted to hospital we were told he was brain dead and nothing more could be done for him. This was extremely heartbreaking and I'm finding this a struggle to deal with. I was told about go fund me in the hope I can get some help to cover the cost of duncans funeral service and burial or cremation as I'm struggling to find the spare funds and would like my dad laid to rest properly so in desperation the only place I could start was on here. the cost of his funeral and cremation or burial I'm looking to raise between £3000- £3500 through quotes I have recieved to lay him to rest. Any help would be very much appreciated and put to good use to help give this wonderful human being the best send off I can.  Thank you for taking the time to read and thank you in advance to anyone if I get further with donations. Im looking to lay him to rest in january but faith and hope will pull me through.
