Help a Single Mom helping herself

I am a single mother of 3 amazing boys. I can sit here and beg for financial assistance in many areas. I am not trying to focus on the things missing because I have 3 reasons to be more than grateful. I am a full time employee in a great company, however I have been behind and have not been able to get ahead. My story is I lost my husband to addiction 3 years ago, I found myself very lost. I was in a very abusive relationship and both of these hitting me back to back set me back. I am and have done the very best I can and God has  met all of my needs and we have been making it. So that being said I was left with two options, a.) Feel sorry for myself and allow these situations to take me out, or b.) keep working on myself and make my life the one I want to live.  I have taken the last 2 years to really heal and learn how to be me. Aside from health issues which nearly robbed my boys of another parent, I am able to and working in a position and for a company that is simply amazing, and a long term life goal of mine, and it is so amazing to feel like I am finally at the beginning of a whole new way  of life  for my boys and I. After leaving the last relationship I was in my car has been ok but it was needing work done. My ex refused to help me with repairs and  he does not pay support of any kind. He is a very sick person and unhealthy for all of us. So I have over 225,000 miles and no air conditioner and in florida that is unbearable. But it has transmission issues and then the windshield in the back was busted out by my ex. Those two repairs alone are 1000+, I need a vehicle my credit isn't the greatest. I need to be able to get to work, my boys to and from school. My oldest son is in a very amazing special programs school, he is brilliant and has a heart of gold. Today is my middle ones birthday and I am doing uber until I have enough to get him a little something. He and my oldest have helped me while I was sick and they are always so respectful and understanding.My little one is 7 and he struggles with behavior issues from his dad and my part in the toxic relationship we were in. All this to say I am not begging for money because I have mismanaged, but I have little help no financial sources and I am having trouble getting financed bc I have little credit and it is not the best. But I am trying and hey I figured I make the post and be honest and I will be doing my part, it won't make my situation worse if I post and nothing comes of it. So here I am. I just know I deserve a car to travel safely with my boys in. I am looking in the under 15000 range and its looking like I will need min 500 deposit for approval and financing and up to a 1500 down payment. I could really use some help, if not well I know God will give it to me at the right time. Ideally I can drive one home today if I am able to get 1000. However I am grateful for all that is given or even someone reading  this.  Here is my paypal information and cash app venmo or chime
