OVERWHELMED by stress!!!! NEED advice!

I’m 18 years old and I’m struggling right now in life emotionally, physically and financially. I’ve had such a rough year so far. I feel like my life is just a revolving door- problem after problem after problem. I’ll try to name my biggest stressors: Number #1 family problems. My family and I aren’t close, and the dysfunction and toxicity in my household is high. I’ve kind of accepted it by now but it still takes a toll on me sometimes. Two: About 6 months ago I got into a car accident. A guy ran a stop sign and my car was totaled. The whole insurance situation was a nightmare, but after all that my parents forced me to use the insurance money to repair my car EVEN THOUGH I DIDNT WANT TO, because I know how many repairs it needed and for it being a 2006 model with 200k miles I didn’t think it was worth it. But they pressured me into it and hired a random “friend” who I’ve never seen before work on it in his yard. Long story short after 3 months we thought he just took off with my car because we hadn’t heard back in a while, he would either ignore us or say “2 more weeks”. It was super sketchy and to cut to the chase I finally got it back and registered it. I just drove it for the first time and I’m overwhelmed by everything I have to fix already!!! MY AC IS BLOWING OUT HOT AIR AND THE AC FREEZE ISNT HELPING, THE WINDSHIELD HAS A HUGE CRACK, MY STICKER IS EXPIRED, I NEED AN OIL CHANGE BUT I HAVE A LEAK, AND THE INTERNAL LIGHTS ARE OUT AND ONE HEADLIGHT!! Like I’m beyond stressed about my car... and 3rd stressor is MONEY. I’m struggling to save up for a laptop and books for university and I’m just defeated! Every time I save up an unexpected cost occurs and I’m back to square zero. It feels like in my life I take 5 steps forward to go 10 steps back. I’m struggling financially and the day to day worry about how I’m going to pay my bills and go to school and fix my car is overwhelming!!! I have debt, car repairs, bills, tuition.... like I don’t know what to do with myself. I can’t catch up. I feel like I shouldn’t even go to school right now because I can’t afford it. Last stressor is my health. During the beginning of the year I had surgery and now my chronic back pain is worsening to the point where I can’t even bend down to tie my shoes. Working as a CNA with my chronic pain is excruciating but that’s what will pay me a little more than minimum wage so I deal with it. I was going to chiro and he made it worse. Then went to physical therapy Once and couldn’t afford the co pays so stopped going. Basically my life struggles are a cycle that I’m having troubling breaking out of because I just can’t seem to catch up!!! I feel like I’m chasing chasing chasing and getting nowhere. I want to give up most days. I’m so tired of feeling this constant pressure and it feels like I’m never going to break out of this rut. On top of it I struggle alone and have no one to vent to. I’m tired of crying every night because I don’t know what I’m going to do. I feel like giving up because there’s nothing I can physically do anymore. I’m a stupid 18 year old that can’t care of myself or sustain myself. I just feel dumb and defeated.
