birth control
"I have been on this pill for 10 days, purposely did not take it yesterday and already feel better today.  I have had a headache every day on this pill, sensitivity to light, nausea, and heart palpitations. Then the anxiety started setting in, and I felt detached from reality. I have a lot of stress in my life but have always been able to manage it.  I almost passed out while driving and went to the ER and have had every test known to man and everything is normal.  Yesterday I had a panic attack.  I have never had symptoms of anxiety or depression apart from normal stress and a bit of sadness after giving birth to my kids.  I know everyone's body reacts differently, but it took me several days to even consider this could be my birth control."
