Please help! I need to feel like a useful mommy and human again!

Depressed and feeling hopeless
Please if there is anyone out there with the ability to help change my life right this moment I could really use you right now! I left a very mentally abusing 25-year marriage with four children and about a week later lost my job due to my car breaking down and then I lost the place I was staying due to my inability to pay the rent because I lost my job. All of this happened so quickly for me that I feel like I'm probably severely depressed but really don't want to admit that or say that I am depressed I just need a way to get back on my feet and every way I turn is the wrong way so I'm hoping that maybe somebody could help me out with a payment one time that would give me the ability to buy a car and get a roof over my head so that I can get a good job and be the mom that I know I can be! I would be forever grateful and appreciative of anyone and any amount of help. Thank you so much for reading my thread and I pray and hope this works it's kind of my last ditch effort to reach out for help. Because all other options have failed me so horribly. I don't want to be a homeless person anymore I don't want to be unproductive I don't want to be a beggar please help me.
