On the verge of deep depression and anxiety PLS HELP ME

I was diagnosed with pcos last year at 18 years old after multiple tests and blood tests. Although I was eating healthy, going to gym 6-7 times a week and leading an active lifestyle I have never lost any weight but rather gained and have been begging for the pounds to come off for the sake of my health. My family is always fat shaming me- especially my father who does not know much about PCOS, even though I try to educate him all the damn time. I’m sick of being in this body and being fat shamed!! I’m currently in my bedroom crying my heart out because I’m just sick of it and having all these side effects with it- ITS JUST NOT FAIR!! I want to lose the damn weight and have a normal functioning hormonal system like everyone else!! Why does this happen to me!! Why can’t I have a nice body and a nice boyfriend and a family who accepts me for who I am?!! I am sick and tired of this. I know keto seems to be the way to go but my family doesn’t allow me to follow it. DOES ANYONE HAVE GOOD TIPS FOR SHEDDING THE WEIGHT AND EXERCISE? I thought I was doing well enough but apparently not. Today my Fitbit says I have burned 3250 calories but I have only eaten half of that!! WHY DOES THIS HAPPEN TO ME

P.S- PLS DO NOT SAY UNNICE THINGS TO ME BC THIS WILL BREAK ME- I ONLY NEED SUPPORT RIGHT NOW THANKS FOR LISTENING TO MY RANT, IM SO GRATEFUL FOR THIS COMMUNITY ❤️
