Good morning:
Cancer treatment can be rough. As a caregiver of a survivor I can attest that the recovery process can be a challenge. It can take a long time. Some changes can be reversed more quickly than others but as another person who posted on this thread indicated, be grateful for what you have—your life and hope for the future. My advice to you is to be kind to yourself and be patient. Eat healthily, get lots of rest, exercise to speed recovery and get involved in some new activities or travel to shift your thoughts in a more positive direction.
All the best.
