PCOS struggles?

I was hoping some of you ladies with PCOS could help me out? I haven’t been diagnosed with PCOS but I do believe I have it. My friend has it and we were talking and most of our symptoms are the same. I’ve struggled since I was 16 with a lot of it but my ob just threw me on birth control for a “hormone imbalance” but lately even with birth control a lot of the symptoms are worsening. I have hair growth (stomach, arms, side burns, toes, a little mustache it’s terrible) my hair falls out easily, before bc pills my periods was no existent or just really terrible and lasts forever, I have weird stomach pains (like period cramps) randomly, I’m overweight and can’t seem to shake the weight no matter how hard I diet or exercise. I just feel defeated.
