Mourning, single new mom trying to find good again

I have always worked hard in life. I got straight A's in high school, and over a 3.0GPA in college. After I was hired at an amazing company that offered a decent salary and benefits, I thought my life was about to turn around. I had been unemployed for several months, and was sent to collections on three credit cards. I moved to South Denver to be close to my job, and looked forward to paying my bills off. Unfortunately, the world stopped spinning when my younger brother was murdered at a house party while trying to save his friend from being stabbed. He died January 12th, but was officially pronounced brain dead January 13th. I was eight months pregnant when it happened. My blood pressure skyrocketed after his death, and I was diagnosed with extreme preeclampsia when I went into labor on January 31st. I was put on a Magnesium Sulfur IV drip and forced to remain in my bed for over 48 hours. I was convinced I was going to die the pain from the medication was so excruciating. My baby girl was born healthy and perfect at 2:19pm on Super Bowl Sunday, February 2nd. Even though I wasn't quite caught up on bills, I knew I would be, and could create an amazing life for my daughter. However, at the end of February, 3 days before I was to return to work, I was laid-off. I scrambled to get any government resource I could. I now have WIC and food stamps, but could not receive unemployment. Until a month ago, I had no luck finding a job. Now I am fighting for hours, but still cannot make enough to pay bills. I've been applying for a second job, which means less time with my 6 month old. I receive threatening messages that my car will be taken everyday, and wasn't able to pay rent for July until a week ago (7/19). I'm scared I will never get above water. I cannot afford deodorant, toilet paper, gas, lotion or soap for my baby, or even any toys for her. I'm heart broken. Not only did my world stop spinning when my younger brother, only 18, was brutally murdered, but now my faith in the world is dwindling. I always believed that if you do good, good will come. So far, I've tried to do everything right, and find myself worried my daughter will grow up in need of necessities. I want to create the best life possible for her, but I can't get my head above water. I need help.
