"i was on this medication for one month and have never felt worse in my entire life. before taking this pill i was an energetic and positive person. now i am exhausted all the time and hit a wall at 4:00 every day. my confidence has plummeted and i am experiencing extreme mood swings/anxiety/depressive symptoms. i have never experienced anxiety prior to taking this birth control and i have had multiple intense panic attacks within the past month. other side effects have been increased heart rate, tight chest/trouble breathing, &amp; chronic headaches. i was put on yaz for my acne and it did help in some sense, but it is not worth feeling like crap 24/7."
