This will make you stronger and smarter! There is no reason in the world any one needs to know about you illness. Once you tell them and it doesn't matter if it's BPD, BP, or ANY THING! They will always look at you different from then on. I tell no one. My wife met me 4 months after I got out of the hospital, at first I said it was because of depression, then I confided in her and told her it was bipolar. SO now when ever I do some thing wrong or get upset it's because I am bipolar. On the plus side we have been together for 16 years. She see's I am highly functional, but have problems some times. Do yourself a favor, don't tell any one. It's not going to help and there is a greater chance you will regret it. Makes no difference what the illness is.
