Delly, everything you mentioned should be thoroughly discussed with your fathers physician. Your father very recently had his surgery. Every patient is different and will react to things in their own way. What you have described is completely normal. It takes time to recover from such an invasive surgery. If you can talk over your concerns with his doctor Im sure they would be able to explain in greater and more specific detail how your father is doing and have a better idea of the end result after he heals.

As a caregiver its so difficult to watch someone you love struggle. I think OC patients really have it rough being OC treatments affect such critical parts of daily living. Being in the patients shoes I know how hard it is to bounce back. Try staying positive and showing a brave face in front of your dad. Im sure he is upset and very scared as well. Hang in there! In time things will get much better.
