I am at the end of my rope and need a little help

Hi, My name is Tiffany and I am 42 years old. This year has been a rough one and I really need a little help in purchasing a car. I got a great job in Austin and moved here from San Antonio in November os 2020. My kids also live here in Austin so I am closer to them as well. They are 20 and 22. After being here a month I fell down a few stairs and broke my ankle. During that time my mom fell and hurt herself. She ended up having a surgery to remove one of her big toes due to gangrene. She became a fall risk and could no longer do things for herself ao I moved her here to Austin with me so I can take care of her. A month later my my 18 year old moved in with me to save money and help him get back on his feet. I started having pain constantly and my wrist was swelling up so bad. I went to the doctor and have been diagnosed with avascular necrosis. That means that I have a bone in my wrist that was not getting blood supply and eventually died. I will be having surgery on that wrist sometime in september. I also was recently diagnosed with Fibromyalgia. I have pain all of the time and I am exhausted. It takes a toll on me. I suffer from anxiety and depression and lately both of those have been amped up. My car started messing up shortly after I moved here. My ABS sensor, airbag, and traction control lights came on and my emergency break light was flashing. I took it to get it looked at and it needed an ABS break sensor.....which were not being made at the time and I was unable to get the part. The part if I could get it is 1200 which I didnt have to pay that anyway. Everything was going wrong one after another and I started having anxiety attacks and was just run down by life. I kept driving my car for almost a year with all of those lights on but eventually it started wearing down. The engine would rev while I was driving down the highway and I would have to put it in neutral while I came to a stop and turn the car off and turn it back on and it would run fine for a few miles and then do it again. It also started using gas up like crazy to where I was putting in 30 dollars a day in gas. At that time I lived 20 miles from my job. It became something I couldn't handle anymore and got rid of it. I was doing ok until my lease was up and moved and now there is no public transportation where I am now. I had to move because the apartments my mom and I were in were HORRIBLE. The management office wouldnt anwser the phone or respond to any maintenance calls. The office was closed so you could never talk to a person face to face. We were without hot water for weeks at a time with no explanation. Then there was a huge rat problem. They put out poison and they all died in the walls and the smell was horrendous. We had to get a motel for a few days because we couldn't stand it. Then about 2 months before we moved they sent out a letter to tell me that one of my neighbors had german cockroaches and they would have to come fumigate. I guess the stuff was strong because we had to be out of the apartment for 6 hours when they come. I feel like everything went wrong for so long that I was starting to get really depressed. My lease was up in March of this year and I couldn't stay there. It was not good for my mental health. So we moved to a better apartment a little closer to my job and that costed me 3,000 due to the rising costs. My rent is now 1750 for a two bedroom. My goal was to save money to get a car, however Uber is exspensive and it costs 30$ one way. 60$ to go to work and back home so I have not been able to save anything. I have to see an orthopedic, rheumatologist, endocrinologist, pain specialist and my primary doctor. Each time I go its a $40 copay plus the uber to get there and back. I just CANT do this anymore. Im loosing my mind. My coworkers give me rides sometimes but I think I have wore out that option and I feel so bad when I have to ask. I have put everything I have into making my life better and the last thing I need to do is get a car and then I will be able to breathe and relax again. During covid I lost my job and my credit took a big hit so I cant buy a car at a dealership without a large down payment or a cosigner and I dont have either one. I also.cant get a loan. I want to just buy an older car outright so I dont have a payment. So I have decided to give this a shot. I never ask for help but I dont see a way out of this without it. Thank you.
