257 hour playthrough.... gone

Decided to start a new game for streaming. Clicked on my 257 hour playthrough accidentally it asked do I want to overwrite I clicked no recognizing that I almost royally fucked up. I started the new playthrough on a separate file. IT STILL DELETED MY OTHER PLAYTHROUGH DESPITE BEING ON A SEPERATE SAVE. I spent the majority of my time fucking around leveling my Henry Strength Agility Vitality Alchemy Stealth Sword Defense Houndmaster and Horsemaster were ALL LEVEL 20. I had over 80k Groschen. I don't think I can ever play this game again. Am I being dramatic or does anyone understand how I feel? EDIT: For clarification because I accidentally left it out. I hadn't finished the story I just got out of the monastery
