yeah, you need some help

On serious note, have you by any chance somehow saved the previous start and end values? Like in history of the shell, terminal or even a piece of paper?
I’ve found out in the past, that if you recreate the partition table as it was, the data will be read fine
Otherwise, you might need to use RescueCd to try and get the partition borers back. But if you haven’t rebooted since that fateful keypress, first focus on trying to get to what partition borders were printed in the terminal earlier. IMO it will be the fastest and easiest
Even if you will get those in cylinders and will have to calculate those back to MBs
