Fed up.. Need encouragement...

So I suffer from PCOS and it causes me to be tired all the time and on top of that I bleed ALL THE TIME.... The only solution my Drs come up with is lose weight (which is hard as hell to do with this condition)or go on Birthcontrol but I also have weight gain when on bc so I hate it. I'm so fed up with being sick and tired all the time... also in regards to losing weight I started a program through a weight loss Dr and I'm down 15 lbs but it hasnt improved my symptoms so far...
