wanting out of my box

Since diagnosis, I feel as though my life has been so limited, stuck in a box that, as D. described it, seems to have spikes in it at every turn and angle. Just want out, almost at the end of treatment - four left, and want to get on a plane and get out of here, go live life and move past this, knowing all the while that I can't and never will. Just, as everyone says to me, a new normal.
