Curious about seeing a Dietician?

So, I’m sure everyone like I am are bombarded with constant GLP-1 commercials, know so many people who took them through med spas etc. and it’s really been getting to me. My BMI it’s like 27 I think? I’m not obese (well maybe by US standards, idk- 5’8” and 190 lbs woman) but I really want to lose weight and keep it off. I’m against yo-yo dieting and I understand I’ve been considered overweight for a while. I’ve been able to lose 30 lbs here and there for years but then I gain it back. This all happened because I went from 116 to like 180 in a few years from being on an antidepressant. That was from disordered eating. I used to eat barely one meal a day, went on that pill and then started unhealthy habits of eating A LOT. Now I eat a protein bar for breakfast, a protein shake, an 80 cal yoghurt and some sun chips for lunch and then usually some rice and ground beef for dinner but then sometimes I crave something sweet so badly I’ll eat ice cream or binge on trail mix… idk what to do anymore. I don’t know how many calories I’m even supposed to be eating or how to stay on a regimen to lose weight and maintain it. It’s frustrating. I’m just sick of it at this point.
