I understand that you have been traumatized by your cat clawing your face, but also try to understand that declawing your cat puts her at a trauma that will be much worse.
Imagine having all your fingernails removed because you accidently poked somebody near their eye. It's crazy.
I've had to get used to sleeping with my door closed since I had open heart surgery and my cat was not allowed to jump on my chest or startle me. Granted, that your studio apartment will be hard to arrange a separate sleeping area, but try to stay calm and figure out a plan that does not involve declawing.
Good Luck !
Please have pets spayed and neutered,
and wearing a collar with an ID tag.
