Past Life Relationships

I want to know my past birth and I think about it all the time, I do not feel at peace until I am able to find it out. Is it possible by doing meditation? This is because there was a lot of karmic debt payment for me in this lifetime and I go crazy thinking why such a thing is happening to me, precisely related to hurt inflicted by someone I love, although this person was not even consciously aware or for that matter even I did not know that I actually love him when I would rather ignore him but he would wait for me when I was not even aware. A series of situations happened which left me completely helpless and I could make nothing out of my life.
