Eating enough?

I'm on day 10 of being on B12 compounded Tirzepatide at 1.5mg. Immediately my hunger and food noise went away, which is truly amazing, but I'm a little worried about how little I want to eat. I've been tracking my calories for the past 5 days and I'm averaging around 1,000 per day. I have PCOS/PMOS and have seen a lot of women warning against putting your body into starvation mode at this low of caloric intake, and how it'll raise my cortisol even more, and even though I'm in a deficit my body will hold on to the fat to try and 'survive'. For reference, at my highest weight I was 282 pounds with maintenance calories around 2,400. Just curious if anyone has any insight on if I need to be forcing myself to eat more.
