What do yall think my actual calorie deficit should be cause I’m confused :/

Ok, so I’m 5’2, female and 241 pounds. I’m interested in just getting down to 200 or so just to improve my health. I have a history of mild ED and don’t wanna go crazy with goal for fear of relapse. I’m also a student with LOTS of homework so getting enough movement is rough. I’ve tried to calculate how much of a calorie deficit I should be in on those apps and websites but it keeps telling me shit like 1200 which just CAN’T be true. I was wondering in y’all’s experience what caloric range I should be in.

I was also looking for food tracking apps that are free and don’t use AI. Also any tips are helpful, especially for keeping weight off and preventing relapse.
