@lonealien,
As long as you keep convincing yourself that you have bad karma you will perceive your life that way.
Just say to yourself, "I have good karma".. reverse the doctrine... there, that was not so hard and don't let yourself be talked out of it.
You are what you eat just as you become what you feed into your mind.
Try not to believe negatives about yourself... they soon become doctrines that begin to be realized in practice.
Reverse the thought and you will become that reality.
Hope this helps.
