I thought it easier, to write a letter (email) to each and every person to whom I wanted to tell about myself. Personal letter to everyone.
It gives time for yourself to gather your thoughts and say just the things that you want and feel that you need to say.
It also gives the person receiving the letter time to digest the things you have written down and if there is a danger that someone goes crazy from this, they usually calm down and start to think a bit when they start to write a reply or in a time, when they search the phone and choose your number.
And of course you don't need to actually send it if you dont like to. You can print it out and give it in person. Which ever feels better to you.
