Help a Dedicated Father Reclaim Stability

I have always been able to stand on my own two feet but this time around I'm fearing of crumbling because I have exhausting all my options. I was recently in a ten year relationship which we separated almost a year ago in which I left with absolutely nothing because everything that i had i left to my kids moms to keep her ahead while i figure myself out on my own.. the last year has been a struggle sleeping outside, at hotels, and different people residence to stay afloat and to save some money to be able to get another car and to put a roof over my head.. through the grace of God I made it happen. I am a father of 4 beautiful daughters that I love dearly. Through the year of me getting myself back together I wasn't able to see my kids often because I did not have anywhere to take them where i felt comfortable with them being at because I was going house to house. So once I was able to get my own apartment my only thought was to get all my girls together to come stay with me for the summer in which I did. I don't receive any govt assistance( food stamps) so this whole summer I have been in and out of the grocery store to purchase groceries with cash and also clothing and etc to make my daughters comfortable. It has got overwhelming because the money used on them was coming out of the money for my bills and I could not sustain it with everything hitting me at once and tryna play catchup.. I woke up this morning with my car repoed for falling behind on payments.. I work everyday but my job is based on transportation and going house to house. I do maintenance and home improvement but without my car I can't do anything. I have came a long long way just to have everything snatched from under me all because I wanted to be a good father and have all my kids together under 1 roof. I'm very good at what I do I paint, do floors, carpentry, general repairs you name it. I'm willing to work discounted prices or anything I need to do to raise this money up.. I don't never ask for help but this is one of those occasions where life is lifing and I can't do it alone in the time frame I need it done i need my car to be able to keep up.. I get paid Friday but I'm still short anything will help please I wouldn't ask if I wasn't desperate
