I want to hear success stories of those who went through actual hell and extremely tough situations and overcame them

As a 20 year old sophomore in college it seems like nothing is working out in my life socially, academically, career wise, and I feel constant existential dread since I was 15 years old. Seems like my life is a constant grind with no light at the end of the tunnel and the struggle. It's like I keep losing and losing and losing every step of the way.

I want to hear some stories of people who went through really bad times and things got better eventually to get some hope and inspiration to keep pushing forward and improve myself. Those who kept losing time and time again but still persevered and became successful eventually.

What are your inspirational success stories? I would deeply, deeply appreciate to hear them
