How did yall find who you are after unmasking after many years?

Im 35 autistic and ive been in high masking survival mode for so so long. When I try to unmask I feel like there is nothing there underneath. I also was taught when I grew up that I shouldnt take up space, speak or be visible or I would be heavily abused by my parents.

And reaching 18 I managed to get away but since then Ive just been trying to survive and reaching out for support to heal and find myself and after a couple of years of that I gave up and started just masking 110 procent. Just going along with whatever people around me wanted.

Now I have had enough of people pleasing, masking, only doing stuff for others but never for myself but I still have this empty space were "I" should be.

Have anyone of yall done the great unmasking and dealt with a empty space inside were you dont know barely anything about yourself

And how did you deal with it and managed to grow yourself inside of that empy space?
