While it is probably a good thing to discuss this with your family, it might not be advisable in all cases. Fortunately people are more open to this than in years past. There are many ways to handle this, and it depends on many variables. All families are different. If doing so seems like a good idea, it is probably best to open up about this to a single very trusted family member first, to see how it is received, and to gain an advocate early on.
