Sudden onslaught symptoms and conditions

I started taking Yasmin 14 months ago and came off it about 2 wks ago and my mood has improved A LOT! I was crying all the time and felt depressed. I put this down to a break up with my boyfriend which was particularly painful but now I feel that the pill had a lot to do with it. About 3 months ago I developed heart palpitations after a night out and have had them regularly ever since. I'm having frequent panic attacks and am convinced that this has to do with the hormones in the pill. Just seems a bit weird they came on all of a sudden and didn't 'develop' over time while taking the pill. Has anybody else had a sudden onslaught of heart palpitations and panic whilst being on Yasmin? I can't wait for it to be completely out of my system! I've read it can take up to three months! S x
