Any success stories of leaving behind everything, hometown, everyone after bad upbringing and starting fresh in another city/country?

So the question is mostly keeping in mind if you grew up in unfavourable conditions - like for myself in a home of addiction/many bad things no kid should be put through I don't know what's allowed to be said here so I'll leave it at that. Moved out at 17 and now 15 years later after a shit show of 20s but then I turned everything around, health, therapy/professional help, moving to a new country and starting my own online business. Things are a lot better.

Yet I'm in my 30s and in a whole new country just building myself back up. I feel progress but boy I can feel behind at times.

Wanted to hear from any that have walked a similar path incase you got words of advice or stories to share on this rainy Thursday?
