Mellay, while I did not personally experience it, I have read that it is very common to have a kind of separation anxiety when treatment stops, as if you are no longer being proactive and giving the cancer a chance to reassert itself. Logically, this makes no sense, of course, but the fear is real. I would recommend a support group, or individual counseling. Many people here have used anti-anxiety meds to help them through. There is help available, and you are not crazy. But congratulations on your good results!

I am sure that someone who has been in the same place you are will respond with helpful advice.

Know that this, too, shall pass.
