You should always tell the truth. Telling them everything is another thing entirely and I'm not sure of the answer to that.....I asked a similar question in the schizoeffective section and the answers led me to believe that keeping some things to myself if fine and even preferred. I will tell them everything when it comes to suicidal intentions because that is life and death but some stuff I think I should keep to myself. Good luck on your decision. (((Hugs)))
