Food poisening symptoms and conditions

im 17 and started Yasmin when i was 14 maybe 15, it made me so sick, id start throwing up about 8 hours after taking the pill, and that would last for about 5 hours, (like having mild food poisoning). I got heart palpitations every minute or so for days on end, and unbearable depression. I was the happiest person until i started taking this pill, and its so bad that i couldn't enjoy my life properly. Now im tiny, like really really thin mums worried i have anorexia, and although my life is perfect (great friend, good grades, nice boyfriend), I cant enjoy any of it properly. I went off it about four months ago and my happiness returns now and then like it used to be three years ago, but my mind feels so fuzzy and sort of disorientated, and i cant seem to convince myself of things properly. I was wondering if these things get better and better or am i stuck like this???
plz help xxx

I have had my Mirena since Jan 07. My periods are certainly much lighter however I am spotting in between. I am having cramping and nausea almost daily know for about a week and my lower back hurts as well. The nausea is what is really bothering me. I don't hear too many complaints about nausea. Is anyone else expierencing this?
Thanks.
