Getting held back by constant hurdles

Ok... Where do I even begin?! Basically I'm a young mum with 3 kids under 4. After my 1st born I got severely ill with ulcerative colitis. I spent a year in & out of hospital getting pumped full of drugs. Eventually I needed life saving surgery to remove half of my insides & give me an ileostomy. It saved my life but my body was ravaged by all the drugs. I now have severe osteoarthritis in my spine, type 2 bipolar (undiagnosed until a break down last year), joint hypermobility & so many other illnesses I could be here all night. I can't work because my health is declining rapidly & I still require at least 2 more operations, I'm learning to drive which I'm flying through but looking at insurance for getting a car in august is sky high. I can't go back in to education because I have no qualifications despite being top of my class in school (I left because of severe bullying). All college courses require some qualifications. At every point of my life where I try to do better I have so many hurdles to face. I feel I'm being discriminated against 😣. And I know feeling sorry for myself won't help but every time I go to do something yet again something comes up. So frustrated!!
