I understand the sense of feeling stuck, and needing to start the next thing. And, trying to have the patience to stick it out. And staying awake at night, wondering and thinking through things... trying to find a way to get all the pieces of the jigsaw puzzle of life to fit together.
I don't really have answers. But, just wanted to say that you're not alone in having those sleepless nights.
I second Zan's feelings of being lost. Sometimes you have to know and feel darkness to find the light.
