A question of rationality part 2 ( self doubt)

 The self doubt aspect. Why is this person so mean to me? What have I done to deserve this? I must be a terrible human being! I do not deserve to be happy! I keep changing my reactions but nothing helps... I am so stupid. Nothing I do will ever be good enough. I have changed my entire life, routines, friends, activities but you still don't trust me! What more can I do to make you feel better! How can I impower you so you feel more secure? 

And then finally, I give up. I will just sit back and pray for an answer. I am just the worst, I am a failure!

And one day all of those feelings become anger, animosity and maybe even hate.
