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.
First off, I'm so sorry you had that much pressure put on you in school. Your father should have helped you and instead he needlessly made things harder. One thing you should keep in mind is a saying I see every now and again: "Comparison is the thief of joy". You're not your brothers or your sisters and that's okay! You may have the same parents, but that doesn't mean you have to be clones.
Distancing yourself from your abusive father was a good move and I applaud you for that! Parents who don't accept their own children, especially including their quirks and flaws, don't deserve them. It sounds like he wants you to be someone else, but tough shit: you're not them, you're you. And you have zero obligation to become this perfect person in your dad's head.
And to answer your question: yes, there is hope. You got out of a bad situation and it sounds like you're still recovering. For now, forget math, grades and employment and just focus on getting better. Good grades and a stable job don't mean jack shit if you're miserable anyway.
