How do you get your "heart" to understand?!?!?!

I was talking with a member on here and this is what was discussed.....

The question, "How do you get rid of the...What the hell just happened? phase?" "How does someone love you one day...discard you the next...move onto someone new as if you never existed?"

It's this question that keeps me stuck....

Ive learned on here that the answer is simple....

These people are not human...they are disordered!! Understanding the disorder is suppose to help us come to the reality that there is NOTHING WRONG WITH US and that we were NOT REJECTED BECAUSE WE WERENT GOOD ENOUGH!!!!! They are not normal...they appear to be in complete charge of themselves and happy but the truth is that they work constantly to mind fuck people to secure supply for themselves....that must be hard work for them, but they dont know any differently and do this with ease.

OK so with all that said....I KNOW all of this...my brain has got it!!!! BUT....how the hell do I get my heart to feel this....I KNOW Im a great companion...whos loving and caring and giving and funny etc. So why the hell does my heart hurt everytime I think of what he did to me?!?!? How do you get your heart to understand all this as your mind does?!?!?

Very Frustrating!!!!
