I felt I needed to come out to everyone face-to-face if I could. In some way I felt I owed them that courtesy. I sent letters to those who live at a distance - other than my daughter, to whom I spoke on the phone.
If you fear they will react violently, then a letter and as much distance as possible would be best.
Coming out is one of the hardest parts of this journey. In general, coming out to each successive person gets a little easier.
But it is your coming-out. You need to handle it the way that suits you best.

Good luck! I hope you get all good reactions.
