My weight loss is similar to yours. I was diagnosed with anorexia with unintended weight loss and was down to 115 literally skin and bones. My body was not taking in nutrients even though I ate all day. I had my feed tube put back in 45 days ago and we adjusted my anti depressant and added olanzapine for Nausea. The side effects for the olanzapine is weight gain, increased hunger and thirst and help sleeping I’ve gained 25 lbs in 33 days and I’m also able to eat things I haven’t ate since my surgery in Dec. 2023.
Maybe something to check into I know how hard eating problems are. Hope you find what you need . Prayers and Gods blessings for you
