I need to ligthen up

I need to lighten up.

This is going to be an interesting holiday season.

I really need to lighten up.

In more than one sense of the word. I am too stressed, and I have too much of a heavy load. When I spent such a long time carrying around a heavy load, going without it seems scary. I have gotten accustomed to my life the way it is. Moving is tedious and expensive. I have to lighten up my load and learn to live with less.
