I'm VERY lucky that my family has always been very supportive, so when I was diagnosed, they stepped up to the plate to help. If your family is not close to you and is not supportive already, I would say it may not help anything to tell them your diagnosis. I only tell people who are VERY close to me and understand me and care about me. I'm so sorry that you don't feel like you have anyone you can confide in. I'm sure you will find those people, and you will know who they are when you do. HUGS!!
