i'm glad your first shot went well amy. i'm proud of you.
i've been on C since '03 and it's gone very well. it does get easier. i had shot reactions (locally) at first but that has subsided very much. and, my MS has been pretty stable.
it will be come routine after a while.
once you get into a system it'll fall into place.
it's ok to be angry. any emotion is normal. i understand. feel free to come here to unload. we get it.
