Lost 2 family members in 8 months

I lost my mom to cancer this past August, and now my brother to suicide May 7th, 2015. I am a single mom of two amazing kids, , Finn (10),Maggie (13) and have a nephew who just lost his Dad (Andy). Pictured above from a few years ago- I was divorced in 2012. I do not receive any monetary support from my children's father. I teach first grade at Beach Court elementary school in North Denver. I adore my job and feel so lucky to touch the lives of students in difficult situations. They are my sunshine, and I truly feel so lucky to have them carry me through each day.
Additionally, I have had 8 back surgeries over the past several years. Many medical bills have followed. I have no paid time off from work, and am temporarily struggling to pay my basic bills, and keep my kids fed and safe. I live in a one bedroom apartment and share a bed with one of my kiddos at night. I know things will get better. But my only sibling died, took his life, and I needed to take a few days off to grieve and support my sister-in law and nephew an my own children through this horrific time. I will not be paid for this time, after having to take time off following my mother's passing.
Setting up this account is causing me so much shame and feels so uncomfortable...but I have to find a way to stay psychologically, physically, and financially healthy, so I can take care of those who need me. I appreciate anything at all.
