Diet is very individualistic. The trick is to eat a healthy diet, which is often easier said than done. As my psc progressed, I started having multiple snacks throughout the day instead of breakfast, lunch and dinner.
As psc progresses, we do not absorb fat-soluble vitamins well. These are vitamins A, D, E and K. So as Mark mentioned, supplements will help.
Fatigue? I usually had naps on the weekend, at least one per day, sometimes, three a day. There were many times I came home and slept for an hour to an hour and a half.
Throughout the day, it was crucial to pace myself, to spread out what energy I had.
Your being a single mom would seem to make it difficult to take the multiple naps. I hope you have some support/family who can take your kid(s) for a few hours.
Speaking of support, it would be of immense help to develop a large support group.
One of the things that helped me the most was the mental aspect of dealing wth psc.
I learned a long time ago in dealing with UC to keep focused on the long term, while dealing with the short term “stuff”. And knowing that psc symptoms can appear at any time.
The best thing about psc is that for most, psc usually develops pretty slowly. But at some point, know that it will become a roller coaster ride.
