Thnk symptoms and conditions

I am really worried! I have taken Yasmin for a year until my doctor switch me to Yaz and Ive been taking that for two years. So for 3 years I have been taken a pill that now has a lawsuit! I have been getting these side effects as well; the tiredness, the vomiting (when my brother and I used to live together, we would eat the same things and sometimes I wont throw it up later, yet he would be fine) I cry a lot! i mean alot! I had people tell me that I may be Bipolar and so I didn't think that these side effects had anything to do with the birth control I have been using for over 3 years. I also had my gallbladder taken out last year and the doctors told me they didn't know why at my age, my gallbladder decided to fail on me. I also have been getting really weird headache on the right bottom back of my head (light a hard tight headache) and now that someone has pointed out nightmares, I have also noticed that since ive been taking yaz i have also been having these weird bizarre dreams every other night or so. again didn't know that this was due to the pill, i thought it was my lack of rest. I also have been experiencing this weird flashing dot in my right eye that has been going on for a year and a half now. Im really worried that these side effects are due to this pill. I don't have a sex drive neither, as a matter of fact, i haven't had sex in two years! I also have that funny 'fluid' feeling in my ears and its been extremely hard to concentrate these past years. Im really worried, I am going to stop taking yaz after this pack is over.
