PCOS worries

Hello, I was recently diagnosed with PCOS. I started gaining a bunch of weight and exercise and dieting never helped. I have hair growth in places that I didn’t know girls could grow hair. I missed my period for several months and my doctor finally did testing. My testosterone is high and many cysts on my ovaries. I am having a very hard time coping with this. I can’t seem to lose weight. I have super bad hips so sometimes working out kills my hips. I plan on doing a calorie deficit but can tend to get light headed. I don’t know what to do about my hair growth. I want to be able to figure out my hair growth and lose 50 ibs. I am also worried about fertility. I was thrown onto birth control again after being off it for a year. We noticed that as soon as I was off birth control that’s when all the weight and hair growth started. If you have any tips and tricks please let me know.
