I think I went into shock …

The trickiest thing is there are so many unknowns with cancer.

You think, How do I fix this?

Is this hurting me?

Is it coming back?

As someone who likes answers, not knowing is one of the hardest things.

Im in a good place and feeling strong.

Its been quite the initiation, and Ill tell you more when Im ready.
