New car and moving expenses

Here I am swallowing my pride and asking for help. The love of my life and my financial support walked out on me and my daughter. I have been stressing and trying to save money so I can move. The car i drive is a 2004 Honda Pilot. Its registered in my exs name. It was having problems with the radiator leaking badly, but today the engine was rattling and then started smoking. I have been putting water in the car every time before I drive it. I only drive it for a maximum of 15 minutes at a time. I have only been able to drive it around town to go grocery shopping and to get to and from work.

• We are currently living paycheck to paycheck. I simply cant work 40 hours every week, I end up struggling immensely with my mental health. I need to move to because my ex wants me out of his house. Hes been staying at his moms and refuses to work things out with me. It's been really hard on us. I'm trying so hard to keep my head above water, but one thing after another keeps happening. When I move, I'll have a roomate to help with bills, but as of now I really need a new car, so I can keep getting to work and help with the uhaul, first months rent, deposit, pet deposit for my 2 small old dogs, and whatever else I am not thinking about right now.
