Finde ich meine Stimme?

Dear Zahohie,
I seem to be unable to hold my tongue and keep my opinions to myself lately. I use to be unable to speak my minds and I could feel the words caught in my throat, so afraid to hurt or be hurt. Now it's changed and I want to let my friends know they are not helping themselves by not changing situations that continue to be problems in there lives. I feel what I say it right but it is so new to me that it almost sounds too harsh, too judgmental. How can I tell when I am talking from my heart not some spiritual superiority place?
