Unemotional whilst on the pill

I just wanted to see whether this has effected others whilst being on the pill. I have been on the pill for nearly 2 years now and sometimes, now most recently it has become often that I go through stages of feeling pretty much nothing and I am numb to emotions. I have recently had to come off the pill and since then I haven't been through any stages of feeling nothing and I started having mood swings in which I actually feel my emotions during it whereas before I couldn't really. I know that there are now being more studies conducted to look into the effects on emotions whilst on the pill as many other women have reported the same sensation. And I was just wondering whether anyone else had suffered this and what they had done to either overcome it or prevent it?
