I wrote earlier and was of the not particularly sensitive ilk - but not mean, telling you that it's a great self fulfilling prophesy the way you've made yourself a cast iron excuse for all failures in life. And once youve for your 'it's not my fault' excuse in place it will encourage you to ever lower and lower expectations and get out clauses so you never have to try and never take responsibility for yourself.
However I'm sure you will have ignored that as you appear to be ignoring anything which isn't allowing you to keep on blaming others and being bitter.
One last go:
I too did the 11+ but no entrance exams as my mother decided I wasn't good enough for private schools in a very 'know your place' type of way. It was a bit of a miscalculation on her part as I found out shortly after I'd scored 100% on the Maths paper and 98% on the English paper, with no tutoring, no special lessons unlike the rest of my (small village) year who all got the private school entrance exam cramming as I went home looking at them through the window as I passed.
The head teacher called my parents in to try and persuade them to get me in front of some fee paying schools pronto but nope, they said I'd struggle later and be teased if I didn't get a scholarship each year and had to drop out into the local comp. oh and besides, it wouldn't be fair to my sister who was two years older.
Was that the defining moment of my life? Did I give up and stop trying as my hideous mother had 'denied me my golden ticket'. Did I resent my sister for stealing my chance? My parents were also poor btw, and no car, isolated village, one year I didn't actually have clothes except school uniform so wasn't allowed out at weekend to 'shame' my parents.
Of course not! I just got on with it, as most others do. And I found out what you needed to do to get into uni, and after lots of hard graft, near misses, almost tragedies and almosts I got there, yes with my shitty comp education and I even managed to screw up my a levels by listening to my parents and taking ones that they wanted me to vs what I was good at... Dropped 2 out of 3 subjects after one year, did 1 a level in 4 months with a teacher kindly giving some pointers occasionally at lunch time - and lending me the text books to dig into myself. And the other a level I just did the final year in and just worked damn hard.
Couldn't apply to my childhood dream of a uni though as I had no mocks to base my predicted grades on. So changed dreams, courses and universities, and got in on interviews and high requested grades instead.
And I got a first, first first in that subject combination in the history of the university. Horrified to find it wasn't enough to launch a great career with (oh dear, a FIRST from a top 10 university not a golden ticket?! The horror! Ok I know it helped but actually no, wasn't a walk in the park and wasn't a instant passport to getting accepted in a profession which loves eloquent, polished, confident stars. Not a northern dodgy comp rags to riches unpolished unsure socially inept raw talent! So I worked my arse off, got experience, kipped on friends floors and did alot of observing of others until I got it.
And sooo, the moral of the story. No lucky breaks. No golden tickets. Just determination, late nights, and a burning desire to do what I wanted to do.
Oh and for the real kicker... Just in case you're STILL thinking I had it better than you... Guess what? No fucking golden tickets. I'm now severely disabled, and am I sitting there on my arse as you put it 'waiting to die', God knows most days I feel like it, but no, I don't take the excuses life gives me to blame others and give up (and ooooh i want to half the time)... still fucking grafting, work part time, from home, made up my own job role that allows me to, had to learn a new skill to do that though, and I manage a crew of carers, nannies and helpers so me and by darling little boy survive. And it's super great, I get the hell of constant pain and disability with the added bonus of society spitting on me for being 'benefit thieving scum' when I still sodding work! No golden tickets
