Yes ngk,
The time it takes to put all the pieces in place is the opportune time for the mind to wander to the dark places. I admit, mine did to an extent.
However, once I started treatments, between the treatments themselves, all the doctors appointments, schedules for taking medications, checking this, that and the other, there wasn't time to dwell on anything else. You're focused on getting through the battle alive.
Tell you what... once you get through treatment, you'll have a new perspective on life I assure you. If you can face the beast and walk away, you can conquer anything, including anxiety.
Positive thoughts and prayers!
