I'm so sorry you feel like you've had no choices. Only way you will change the wait time is to voice your concerns loudly and repeatedly to your oncologist and breast care nurse. If your centre also has a psych onc you can voice your concerns there as well.
You don't have to sit silently resentful - just start voicing your concerns loudly and often.
I have had 12 days of rads in July before quitting them (long story) and had a bilateral mastectomy with immediate reconstruction last week that appears to have worked perfectly.
The squeaky wheel gets the oil is the old saying.
