please help me save my mom's car and help me get back on my feet

I literally never do this but i'm finally at my all time low, ready to give up so this is my last resort. Here is a little bio about my life. I dont really have any friends at all and ALL of my family except my nephews are dead and gone. Those boys are the only reason I'm alive. Unfortunately i can't help them or do anything for them when they need it/if they need it Because I can't do anything for myself anymore. I've never had to have help like this before. So my dad was murdered when I was 13 on Thanksgiving day and with that tragedy so young I done my best to stay ahead in life, be a good person, help others, and for years it worked. I only had me and only needed me. I always worked 3 jobs, had my own place, own car, paid my own bills and was NEVER broke. I would help SO MANY people. Loved ones, strangers, people that didn't think twice to help me back but I did what I could anyways for anyone in any way that I could. Now I'm not only Asking for help but I'm begging for help and it's beyond embarrassing. IVE never needed this kind of help in life because i always had me and now, now I'm drowning so deep i truthfully don't know how to fight anymore.So October 25th 2021 I can bluntly sit here and tell you that my mom was murdered and nothing was done about it and it still affects me everyday of my life. I literally feel like I just lost her yesterday and after I lost her I derailed my life, so flat on my face and Rock bottom doesn't even describe how far down I am and how scared I am that I'll never get back up people that I helped and people that I loved and cared about that I thought that would at least be there for me to talk to or mentally for the ones that destroyed me stabbed me in the back, betrayed me in so many ways beyond belief. Only thing I really have left in my mom is her car and her remains after she was cremated. With that being said her car finally broke down about a month ago now and I've been walking everywhere that's really trying to do what I can to make money to save this car it's a huge piece of her that I have left and it's probably the only thing that can get me back on my feet with a good steady car to have a good steady job again so I'm begging anyone for any kind of help please help me save my mom's car please help me save my life.
