Those who are called to present truth in an uncommon way are often criticized, even condemned, rarely understood, but always of great service. That is you. Know it or not you are self serving in a positive manner. We know this is true because you unselfishly serve others. This you are called to do.
You, like us all, must from time to time feel doubt, even emotional pain. It goes with the territory and serves its good purpose. Bear with it. You are serving your purpose, obeying the Will.
Bless you, dear friend.
