Period problems

I have been diagnosed with Secondary Amenorrhea. If you dont know what it is here is an explanation:

"Secondary amenorrhea is a term used when a young woman has had a period before, but stops having them. For example, your periods were regular for the first 2 years after you started having them, and now they don’t come at all. Or you only have 2 or 3 periods a year and sometimes 6 months goes by without a period."

For me I go 6 months to a year without a period. I have gained weight due to it and it didn't used to be this way. I went on birth control pills and had normal periods every month. But, my doctor decided to be a bitch and kept putting my on a different birth control pill every single month which started to make me sick. I stopped seeing that doctor and have been trying to get into a different one except that she won't transfer my medical records. Now I have been without a period for almost a year.

Do you have this? I was just wondering if I am alone in this struggle.
