Hi Bobd,
The depression after treatment ends was one of the few times that my husband and family didn't understand me and my feelings. As caregivers, they were ready to move on, it was OVER, I was better, door shut. But for the patient, it's not that simple as it's our life that we were fighting to save, every day with treatment.........and now treatment was done. And we're so tired from the physical effects, the emotional effects, we want to feel better and were expecting to feel better and that doesn't happen. It was one of the few times that I didn't have the energy to put the feelings of my family first, mine were swallowing me up and I simply couldn't think of anyone but myself. It was short lived but very intense.
Ride it out, talk to your doctor about it and KNOW that it's normal.
Good luck,
Minnie
