CAR NEEDS FIXING, RENT NEEDS TO BE PAID.. LONG YEAR!

My car has been stopping on me while driving, and with my son in the car. A lot of money I had saved I used when my daughter passed away. This is a stressful year.  I have a job I may get suspended from because I wasn't able to make it due to no car, no extra cash for cab and extreme weather here in Chicago.  I just need help to get car fixed and have extra for rent that's already late so we don't get evicted into this cold weather. What do you do when you've done all you can?  Feeling helpless!
