It’s like a switch deep inside me. I can turn it on, but it’s more common for me to turn it off.  

Two whole years had passed by since we had last seen my dad. I had just arrived in Florida, along with my two young children, when my dad called to say that he was driving through the area. I was thrilled. He then went on to mention that he could only stop by long enough to have lunch. Only lunch? Only an hour or two of the day? I felt the loss and sadness begin to well up, so I threw my switch to the “off” position.

Making a mountain out of a mole hill!  

This is an English idiom used when someone appears to be exaggerating a situation.  It can happen externally where others see it, or it can happen internally where only I notice the mountain growing inside of me.
