Leukemia treatment can be heavy for the patient in both a
physical and psychological way. Spending a long time in
isolation is hard and it is easy to lose motivation. Let your
friends or relatives know that you are there for them, let them
know how much you miss them and that you want them back with you
soon, so they never lose sight of what beautiful prize awaits
them if they hold on: going back to life.
Keep in mind that leukemia patients have a higher than normal probability of getting sick, because chemotherapy lowers their white cells count (the cells that fight infections in the body), so you will have to wash your hands more often, and if you have a runny nose or a cough be sure to keep your distance. They will also be weaker than usual and they may not be able to take part to all activities.
Make sure you organize or invite them to activities they are able to do.
