L.T.
God bless you. I will pray for you. The advice I am going to give is taken from my experiences with my son who has leukemia, my SIL who had Hodgkins and a friend who is battling cervical cancer.
Frequent hand washing and hand santizing is important - for everyone. Insist that everyone wash their hands upon entering your house.
Don't be afraid to hurt anyone's feelings by opting out of gatherings if someone who is attending is or has been ill recently. I realize that isn't always possible, but our rule of thumb was to err on the side of caution. We found everyone to be understanding. Even if nobody was sick at the time, we opted out of holiday gatherings during cold and flu season to avoid any germs the 12 nieces and nephews might have been carrying.
Talk to your oncologist about possibly taking antiviral medication.
Accept help from others to run errands, make meals, handle household chores so you can save your energy to fight your illness and spend quality time with your family.
Nap when your son does and also when he is at daycare. Save your energy for family time.
I remember when my son was going through the most difficult phases of his treatment and he was often neutropenic we weren't allowed to have plants in the house because they could harbor mold that could make him sick.
Check with the American Cancer Society and other such organziations. They have good informational booklets about caring for yourself emotionally, physically, nutritionally, spiritually, etc.
Look into local support groups for yourself and your family. Gilda's House is one that offers many different types of support and social events. They have quiet rooms, rec rooms, etc. Many people find it to have a very nurturing atmosphere.
Look for something positive in your life each day - your son's smile, the sunshine, a good medical report, a kiss from your husband, comfortable pj's. ;) It will help to keep your spirits up in light of the battles you are facing.
If you have any questions please send me a message. If I think of anything else, I'll contact you. I'll be praying for peace and strength for you and your family.
