Residential or IOP or Dietician? Experiences / Opinions

About to turn 50 and thinking I may be ready to make some changes after 30 years of ED and recent therapy for complex PTSD. Tried a dietician but freaked out after one appointment and my therapist thinks residential might be what I need in order to totally disrupt current patterns. It’s complicated because I am the bread winner and have 4 kids (2 in college, 2 middle school). Feeling stuck / lost and looking for advice.
