Hello Kim,

Like some of the other members mention your dad is suffering from depression. Going thru this ordeal is alot more than just the physical part.
Take Marks advice and get him a thyroid test. Most of us take anti-depressant medicine. It's a normal after effect of treatment. Our old lives no longer exists. Your old father is still there he just can't be the person he was prior to the treatment. Sounds like he had major surgery.

We have to adjust to our new lives after cancer treatment. I was so happy for him to survive this 2 years with no signs of a reoccurance. That alone is a major milestone.

I wish him the best, Dan
