You could try Testdisk[1]. It may help. The data on a SSD is no= t
necessarily stored linar so it's not said that a new partition is using=
the same memory cells as the old one. Even if it is, you'd lose any
information about directories or files (names, dates, accessrights and
so on).
You should definitly try to minimize writes (ideally there would be
none) since they can corrupt data. For a HDD I'd advise to create a cop= y
using dd but from my understanding of SSD technology it's not
guaranteed to copy the right (now unused marked) blocks.
If you can't recover the old partition information I'd say you lost= your
data unless you are willing (and there's no guarantees either) to pay substantial amounts of money to specialised services (substantial as in
most likely >> 1000 EUR).

Thanks for the input. I ensured that there is no= write after I noticed the partition was missing.
I try what I can now, and I'm sure its gonna be a long night
