Are you ever surprised by the intensity of your emotions?

After a night of intense discussion between myself and my SO, I am at the point of debriefing with myself, trying to process exactly what happened, and trying to obtain some insight about where to from here, I find myself surprised and maybe a bit overwhelmed by my emotional reactions. It seems that, even though I like to think I am in control of myself and understand what makes me tick, I find myself surprised by the intensity of some of my reactions. Have you had a similar experience?
