Ground shifting.
Some changes are incremental. They grow on you over time. You can become used to them.
And then some are drastic. Like moving apartments. There is no incremental version. It all happens in one go.
And it changes so much. The ground under your feet is literally shifting.
The key is to find the grounding within. To know that you got it. You can move through it. You can get to the other side.
And once you are there, you can start building again.
