Melancholic symptoms and conditions

So i began taking the birth control pill as a way to regulate my period and decrease cramping. Needless to say, i started with Alesse and all was fine, except i broke out badly on my back (i have never had acne especially in that area before).. so i switched to Yasmin and have been on it for a few months. Yasmin was great in removing the acne and regulating my period. I now have it for 4 days instead of 6 and my cramps are entirely gone. Recently however i began experiencing headaches and slight bouts of depression. The depression isn't very extreme, but i am feeling a lot more tired than usual, i'm sleeping a lot, and most importantly i've been feeling melancholic and indifferent about things. Therefore i have decided to stop taking it as of today (during my pack) and see if my mood changes. It isn't worth doing this to yourself.
