Hi Nicole,
congratulations on the completion of your treatment, I hope that you have fared well through the radiation. I do remember the feeling of what next when mine was finished, it was so strange.
My husband and went on holiday just after my treatment was finished, we spend 2 weeks in Cairns, I wanted some sun on my skin. To be honest the holiday helped us both ease back into life.
Don't put any expectations on yourself, it takes some time for life to find a balance again.
Just take it one step at a time and you will get there.
Donna
