I don't like when people treat me differently after I tell them about my illness
when I tell a friend about my illness
when I confide in a friend about my illness *病気のことは大体秘密であれば
友達に病気のことを打ち明ける
I don't like when people treat me differently
(他人に)変に気を使われるのもいやだ
直訳的に「I don't like when people weirdly fuss over me」とかになりますが、こう言う場合はtreat me differently(今までと違う扱いをされる)をよく言いますね。
ご参考になれば幸いです。
