Completely loosing all hope

I (23F, 240lbs, 5"9) finally had an appt with my my gyno this week to tell her that metformin did absolutely nothing for me other than make me dizzy so we talked about starting ozempic. I was so relieved that a doctor was finally taking me weight seriously, I was so happy, but then she told me to talk to my family doctor about it then rushed me out the door. My family doctor is a 57 year old male asshole who's favourite diagnosis is "women experience stress differently" I swear my foot could be falling off and he'd say that it's from women experiencing stress differently from men.

I talked to him and all he did was send me for blood work and refer me to a weight loss clinic that I think is going to be a huge waste of time. I've tried diets, exercise, calorie deficit, inositol, metformin, everything and I'm still gaining ridiculous amounts of weight. And I can't even starve myself because I get so light headed if I don't eat after a couple hours and I'm constantly starving or if I eat enough to be full it'll only last like half an hour.

In August I weighed 220lbs and now in October I'm 240lbs and a pair of jeans that I bought in September won't even do up on me and I didn't even get a chance to wear them.

I'm so miserable. I don't even like to leave the house because of my body. I don't have any friends and I'm single and it's because of my weight. I'm only 23, I should be out all the time instead of being at home googling PCOS weight loss tips 24/7. No one understands how hard it is being fat when you're trying everything you can go lose weight. It's severely effecting my mental health, I can't keep living like this.

I just don't know what to do. I want to not despise my body. I want to wear clothes that a 23 year old would wear instead of just buying whatever ugly thing fits. I want to go out and not think about my body the whole time. I want to make friends and get a girlfriend.

I'm sorry for the rant but you guys are the only ones that'll understand.
