How do I retrieve my lost scores?

so, i created a score, specifically a song for my dearest friends for valentines, and so you know the drill. but stupidly, i forgot to save, and once i accidentally got a laptop crash, i didnt think of the score first. when i wanted to make a new song, i saw the option to "restore previous scores?" i unfortunately didnt think much and just declined. i then forgot a i had a song for them, checked all of my files, turns out when i went to the diagnostic options and to the file paths, i didnt even have a backup folder. and i really need that song back, but i dont even think its possible. does anybody have an idea to retrieve it or do i just have to restart from scratch?
