Keratoconus symptoms and conditions

I have been on Yasmin for 2 years and i was recently diagnosed with an eye disease called keratoconus which is loss of vision and cornea problems and Yasmin might have been the cause of it. I also have had excessive weight gain that i can get rid of, depression, sleeping problems, and hair loss. I am concerned because i do not know if it is healthy to just stop taking birth control but i don't want to do more harm to my body.
