I'm starting to think that my life is over and I don't want to live anymore. As of writing this I am a 23 year old woman with no qualifications or education. I have learning disabilities and my IQ is just 76. I struggle with things like talking, maths and spelling and I can't find a job.
When I was a kid I knew I was different. Things that were easy for the other kids to do took me ages to learn. Kids used to make fun of me because of the way I talked and in general I could fit in. As I got older my learning disabilities become more noticeable. I was diagnosed with ADHD and low intelligence and therefore struggled academically but my dad refused to put me in a special education program because he thought it would be an embarrassment. School was very hard for me. I would work my ass off just to get C's and B's and my father was very abusive. He would expect me to do well in school and if I didn't he would beat and punish me. I had to repeat the 7th and 9th grade but I eventually graduated but very poor grades and no qualifications. When I was around 15-18 started to do drugs like weed and alcohol just to cope.
I left my parents house when I was 19 and went to live with a friend. I have very little money as I'm addicted to drugs and my lack of education makes getting a job practically impossible. I don't see my life going anywhere and when I'm not on drugs I'm miserable. My brothers and sisters have done so much better then me and it makes me so jealous, angry and ashamed. I know this may sound cringe but I honestly can't do this anymore.
EDIT: I now have a job at Burger King as a cook. It's not glamorous but it's some money.

I'm a bit over twice your age though, so I'm speaking based on my experience in life.
All those occupations you listed require very specific types of intelligence. I fully agree with the poster above who said that there are many different types of intelligence. To expand on that a little, someone may be the best car mechanic or cook in town but be a terrible programmer or nurse. And vice-versa, a great programmer may be a terrible nurse, mechanic, cook, etc. The idea that IQ is anywhere near a full measure of someone's abilities is truly, completely wrong.
Don't let the fact that you "couldn't" do those things stop you from trying a myriad of other occupations where you may be successful and find fulfillment. If you believe that you can only be successful or fulfilled by being good at one of the latest occupations trending in media, please don't. Someone can be successful and fulfilled doing pretty much just about anything. Some examples: building trades, mechanic, driver, janitor, cashier, cook, bartender, hairdresser, anything. FYI, I've heard that in France, people in any occupation demand and get the respect they deserve for being experts in whatever occupation they chose for themselves. Just as an example, my hairdresser told me an amusing story of arriving in Paris and stopping at a fruit stall where she promptly started to squeeze the fruit like we do in the US. The fruit stall minder literally smacked the fruit out of her hand and selected the fruit for her. He was the expert in fruit and she had no business picking the fruit herself.
It sounds like your main issues probably stem from your father's neglect and abuse and perhaps your ADHD and other learning disabilities, not from your IQ. You would do well to address your drug addiction first with whatever treatment options are available to you (this would also impact your IQ test scores, but do yourself a favor and forget about IQ). After that, or maybe at the same time, if you didn't graduate high school, work towards getting your GED. After that, enroll in community college and take whatever variation of "succeeding in college" (study skills) and "career exploration" classes they offer as your very first classes. After that, many options should present themselves to you in community college. Focus on the careers that you can do with either only a high school / GED diploma, or that plus trade school or community college. Many community colleges also provide mental health counseling and assistance finding jobs. Take advantage of any opportunity you encounter.
I, like apparently many others here, believe in you! The answer to your question is yes, there is hope for you!
