It's sad that you clearly got an untrained tech and she caused this kind of damage to your nails.
You give the impression that because of how bad your nails are from having Bo Sculpture, this is why you went and trained with Gelish instead.
Please don't blame Bio Sculpture as a product/brand, Bio Sculpture did nothing wrong, the tech did all this damage.
The same thing or similar could also happen with Gelish if the tech applying it is untrained.
A situation like this would have made me determined to go train in Bio Sculpture not change systems all together but that's me
and then I would go back to that tech and say "look what you did and now I know exactly what you did wrong"
Your nails should recover it will just take time, looking at the damage I would guess a good year before you see a full normal nail again.
Just keep them short, make sure they receive all the moisture/oil they need by using a good quality cuticle oil and just generally show them some TLC and all should come right.
Also make sure that you yourself as the trained Gelish tech, do the Gelish service exactly how you were trained to do it and this way, you yourself should not cause any further damage.
Good luck
