Biological Reasons Breakups Suck
I think when it comes to the end of a relationship, our physical and chemical bodies are on the side of our ex.
At least it certainly feels that way as they both seem to do everything in their power to make the bad practically unbearable.
The good thing, as with your ex’s behavior, once you begin to understand why your body is doing what it is doing, it’s a little easier to distance yourself from its tantrums and not take them as gospel.
So take a read and then hopefully find some comfort in the scientific reasons that you’re having trouble after the end of a relationship.
