Help with funeral expenses for Krystal and kids

No one expects a tragedy to happen like this. My kids and I was not emotionally, physically, or financially prepared for this. Mark and I was married 20 years. We have been together our entire life. He struggled with depression for years. I will never understand how someone can feel so alone and feel like the world would be better  if they were gone.  He was the love of my life, my best friend, and the father to my three beautiful  children. He took his life Saturday June 19.  We have no life insurance on him so we are left with all the expenses. Funeral Cost are a little over 1700.00  Any help would be very much appreciated.
With love,
Krystal, Jayden, Jackson, Jasmine.
