You want to know why you just can’t get over it?
Why you feel stuck or stagnant?
Why change feels impossible?
No change can come from the space in which we suffer. We must drop into where our brains hold the experience, where we have been pained or troubled, shift our awareness to a place of healing and overcoming rather than one of it still happening to you. Then, we can experience emotion and feeling tied to it and move forward from and into a different state of mind. 
The state of mind it is happening to you in, is not the state of mind you heal or overcome from.
