Ortho tricyclin low symptoms and conditions

I am due to start my third pack of YAZ, and I am getting off today. My dr. gave me a three month trial after I switched from ortho-tricyclin low because I had break-through bleeding. I realize with any contraceptive there are going to be side-effects, but this is ridiculous... I have had extreme fatigue, I am sleepy all the time. I also feel like I cannot think clearly, like my head is clogged or something. I also feel very anxious and this feeling like I am going to pass out. Also my eyes feel very dry and unfocused. Nothing is worth feeling like this, and it is very obvious that all these symptoms are coming from this pill. I am scared to try anything else!
