Is it okay to eat 1,000 calories a day for my height?

Hii! I'm 19F, 4'10, and currently weight 120lbs. I used to weigh about 97lbs from when I was about 16 to 18, but I had some traumatic events happen last year and unfortunately stress ate like crazy. I went to therapy and have emotionally healed, but now I would really love to get back into shape 😁 Unfortunately, I really do feel so fat right now 😅 I'm going to try to go about this as healthy as possible, but I would love some tips. I've never had to loose weight before haha
