Raising Funeral costs for my beloved mother

My mother lost her battle with brain cancer yesterday, 12/22/2018. 
It was a painful experience for her and her children. 
We loved her dearly. 
My brother and I sat down with the funeral director and we are at a complete loss as to how we are going to be able to handle this process.
Derek and Caitlin are the only family left of Sonia’s.
$4,000 is the minimum we need to have her cremeated and given to us. 
I’d wish for a locket of some sort to hold her ashes with me at all times. 
Caitlin took her time off of work for 7 months to take care of her mother full time. 
This whole year has been tons of losses to us financially, and losing loved ones, and I feel so silly asking for help. 
From losing our money on what was suppose to a beautiful trip to Bermuda, turned in to a 4 week hospital stay, overseas and alone, with no refund. 
Last month, my vehicle was broken in to, and everything inside was stolen, 2 wallets, debit cards, checks, a laptop, phone, iPad, Important documents. 
The debit cards were charged 2k instantly. 
I never thought I would be doing something like this, but I will admit that we need help. 
Any love will be greatly appreciated. 
I am willing to paint some art for those who donate if they desire. 
Thank you. 
I love you all.
