Expert Q&A Preview: How Do I Handle the Abrupt Emotional Changes?

How do I deal with strong emotions that change for no seemingly good reason at all? For example, one day I will feel completely fine, loved, hopeful, happy, grateful for this wake-up call, & motivated to work on us (currently in EMSO) & do the best for my family and in the next moment I will feel disgust, dread, unloved and unloving, like I just want to leave my spouse & start my life over, one that I deserve. I'm the betrayed spouse.
