I 've always been an emotional person, but usually in a good way, you know, crying during movies, or when I saw a cute old couple. As I got a little older (18, 19, 20, 21), I noticed I was exhibiting almost bi-polar behavior, especially around the time of my period. This was very odd for me because I never even had slight PMS when I was younger.
I would go completely berserk for almost no reason. One time I was working out, and in the middle of a rep I just burst out crying. I couldn't handle any negative triggers if I was drunk or high- I'd go into complete meltdown. I became pretty irrational and would go in and out of depression constantly. This went on over the course of about 4 years.
I recently went off my birth control pills which I had been taking since I was 16 (I'm now 22), and the past few months have been really nice. I feel stable, I don't cry every week, and haven't been randomly depressed over nothing. I know this doesn't mean the pill was responsible for my emotions 100%, but considering that nothing else in my life had changed to stabilize me, I wouldn't be surprised if it was the major culprit.
