I find that, as a playwright, putting stage directions -- how the character feels, etc. -- helps ME. I'm the author and if the actor does not like it, tough. It is possible your character does things in such a way that is quite unknown to the actor.
And don't worry -- actors are quite capable of ignoring what the script says!
You could always put 'em in when you write the script and take 'em out of the final draft.
