I want to hear stories of people who went through 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.

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.

Would deeply appreciate to hear your success stories
