Not being able to loose weight is killing me

27F, Aus based

I'm the heaviest I've ever been and continue to gain.

I have EDS which mainly manifests as gastroparesis and dislocations. Thanks to being made of silly string I can't exercise every single day to burn the cals that way.

I eat max 1500 cals on a weekend, 900-1200ish during the week so cutting back on food isn't an option. I'm also barely hungry.

I have tried EVERYTHING healthy to loose this weight and nothing works. I worked with a dietician for a year, tried heaps of different exercise regimes... I hate leaving the house, none of my clothes fit and I can't have sex with my boyfriend. I feel so revolted by my appearance.

Can I take more thyroxine to put myself hyper? Can I go on Ozempic? Do I see a naturopath? Do I fast?

I cannot keep going like this and I need external help, whether that be from medication or something else. At this point, I don't actually care if it's unhealthy because every day I'm like this my mental health, relationship and work life suffers.

Please help.
