i think everything your husband is going through is completely normal. although, i never vomitted, i did have the nausea and the fatigue. the more my treatment went on the worse the fatique got. i also have small children...at the time, they were 3 and 7. it was not easy, but I thank God for my family.....lots of support makes a huge difference in fighting the battle.
as far as feeling sorry for the patient..... i agree....do not feel sorry. show compassion and support, but never sorrow. i know for me, one of the hardest parts in dealing with this was the thought of my loved ones(my mother especially) having to see me go through it. it broke my heart to know they had sorrow for me. they were very strong...i know they felt the pain however, they did their best to hide it and remain confident. i know that helped me tremendously.
