Oh god... when I was on hormonal birth control, it brought my chronic depression to the absolute lowest point in my entire life. I never, ever, EVER want to go back to that place. The brand or hormone combination didn't matter. I couldn't manage my depression or do treatment because I felt like I wasn't in control of my emotions (and I didn't realize it at the time). I didn't attribute it to the birth control until much later. I stopped taking it one day, and two days later I was asking myself if I was possessed for two years. The difference was that dramatic.
That's not to say no one should ever use the pill. Some people work really well or at the best with hormonal birth control, or need it for medical reasons, but I'm not one of those people!
I think I scared every single doctor I've consulted about birth control options because they'll mention something about a low-dose pill and I would panic at them in a loud voice. "UH, NO. I DON'T CARE HOW LOW THE DOSE IS YOU NEED TO STOP RIGHT NOW I THOUGHT YOU WERE HERE TO HELP ME."
The non-hormonal options are nearly zero and the only non-invasive ones I've found are condoms, diaphragms and the copper IUD. :S Woe.
