Frustrated with the lack of support and guidance from my GP (rant)

I'm trying to work with my current GP on my weight issue, but I feel like I'm not getting anywhere.

I have tried Saxenda (online GP) with little progress, egg burps and significant abdominal pain. My current GP won't prescribe any of the glp1s for weight loss because they could cause a dangerous drop in BGL (apparently someone died that way). He also won't prescribe Phentermine because it could cause a heart attack. He gave me Metformin which did nothing. Last time I asked about my options he told me I'd be better off with a bypass even if the upfront cost seems huge. I don't think I can live with severely restricted intake for life, but from what I can see, bypass requires a preop diet of vlcd shakes. I asked - since bypass is a good option - why I can't test the vlcd under supervision. He said the risk of deficiencies (Na, K) is too high.

What the fuck?

He wants me to be on the CSIRO total wellbeing diet if any because its "backed by solid research". That diet requires membership fees ($39-79/m) on top of expensive shakes and meals. How is it any different to any other shake based diet?

I'm starting to feel like he is just being obstructive instead of helpful. Usually doctors are at me about my weight at every appointment; how I'm so lucky because it's so amazing that I'm still "healthy" BUT if I don't change I will die... but he's not pushing that narrative and also seems reluctant to help.

What am I meant to do?

I want someone to work with me, to guide me, to check my health regularly. I want someone willing to try different approaches. I feel like he's not doing that, but why? If he gave me a reason like "it could trigger your seizures" I'd understand, but it's all very general.

I don't want to switch because he's so good in other areas. I don't want to have to "doctor shop".

Do any of you have advice on finding support and guidance through healthcare? Do I have options besides finding a different doctor? Are there any resources in Australia for support? I don't want to go online again just for a two minute session and a script with no thought.
