Releasing and feeling exhausted

I just wondered if anyone else has had the same experience.

This morning, I had a very powerful and big realization about an illusion I've created and lived in for more than 25 years. That illusion made me feel miserable and very judgmental towards myself and my self-worth. This morning, I saw it all for what it was. I saw all the damage it was doing to me on many different levels. I saw how it was blocking me and keeping me from moving forward and opening to my True Self. And I released it. I stepped out of it.

As I was releasing, I cried and I also smiled. I felt how deeply important that experience was. I felt grateful, deeply grateful because I don't know how else I could have understood that knowledge. It was a very big but also very precious moment.

Right after, I felt deeply exhausted. I still am exhausted as I write these words and I feel like it is going to be one of those days where I would just go back to bed and sleep all day (which I can't do because I'm working... at least my job is pretty cool so it's not such a big problem).

My question is: Has anyone else felt such immediate exhaustion right after releasing or letting go of something big that was really hindering them in their lives?
