Microgynon 30 ED pill and weight loss

i started using microgynon 50 ed when i was 12 due to adenomyosis, i am now 20 and still using it. before the pill i had bad acne over my back and face, i was a bit chubby and my periods were extremely heavy (fill up a overnight maxi pad in an hour) and the pain was almost paralysing. when i started taking microgynon, my ob-gyn instructed me to keep taking the hormones constantly, so i haven't had period in around 8 years. over the years, i have lost weight, my acne basically disappeared (i got maybe 1 zit every week in high school, now i rarely get them) and i never spot. However, my mood is very low, i'm sad, agitated and highly irritable all the time and i have no libido at all. overall, it saved my life but i cant help but wonder what the consequences will be when i finally come off it
