Try to eliminate inflammatory foods. Obviously dairy, but also white flour/white bread, white sugar, white potatoes, white rice, etc. anything processed or fried is going to cause more inflammation. Work on eating whole plant based foods, sprouted grains, etc. and consider adding a probiotic to your diet.
Just take your time, don’t look for a quick fix. Start by making one simple change. Looks like you are already on the right path by adapting a plant based diet. You could also cut gluten and still enjoy lots of great healthy carbs. I cut out dairy, gluten, caffeine, alcohol, processed foods, refined sugars etc. it was a process but in the end I have been extremely happy. Exercise when you can, even if it’s a short walk. Just be patient with yourself. I’m a nurse and I have worked with people with similar struggles as well. Everyone is different but there is a light at the end of the tunnel. No matter what is standing in your way, you can do this!!!
Veganidm is a good start, but still try to eliminate processed food. Stick to whole foods. I would also do a bowel cleanse a lot of problems come from leaky gut. Eat goods that would help reverse that issue. Stay away from gluten, oil, sugar, caffeine, and other foods that cause inflammation. You can do it, and you will feel so much better!
I have HS, pcos, & IBS also. It can be done. Work with your endocrinologist to balance hormones. It will make weight loss easier, then use a meal logging app to track your nutrition goals. I do better w 1400-1600 calories per day than 1200 for weight loss. It’s just more sustainable for me. I try to source my calories ~45% carbs ~30% protein and 25% fat, and min 35g fiber.
