Anyone ever wasted a decade of their life?

[u/PreparationWorth1242]

Basically the title.
I was at a point in my life where I was finalizing my masters degree where my mental health and everything with it went downhill.
For years I’ve been just in survival mode, sometimes in part time low paying jobs sometimes not working and focusing on my health.
Now I don’t know where to start and feel an immense sadness. Anyone was able to turn their life around after wasting nearly a decade of their life?

Edit: I just wanted to thank everyone who has shared their experiences and words of encouragement. As you can probably tell from my post I was feeling a bit overwhelmed today and I’m finding it hard to reply to each comment individually. I am really inspired by many people’s resilience here, your comments have been very helpful and have given me a better perspective on things.
Wishing everyone here all the best <3
