I don't think that allowing yourself to feel emotions equates to relinquishing control. In a way, blocking them puts the control with the emotions.

I know I tend to see things as all or nothing. I either trust completrly or not at all. I do things to excess or not at all. So for emotions, it feels like i would do the same thing - either block my emotions or lose control of them entirely. The thing is, it's not (or doesn't have to be) black and white or all or nothing.

There are healthy ways to feel and express emotions. T can help you find that middle ground.
