How to get over the "obligation" to come out to some people?

I know, I'm not OBLIGATED to come out to anyone. Hear me out.Over the past 6 months, I've come out to my 2 best friends, and I just came out to my parents.I'd like to start getting to the part where I live openly. But before I can feel comfortable doing that, there's people who don't live nearby who were really important to my development that I feel the need to be honest with. Certain friends from high school, a lot of friends from college, my roommates, the people in my former a cappella group.You can start to see the problem. It's too many. And it's not like I want to sit down and call each of them to notify them in the same sordid way you would let people know someone just died.It's just that I brazenly lied for so long. And I don't want them to find out via a picture on facebook or a mutual friend who saw my face on Tinder. Not after I insisted so vehemently I was straight, and lot of these people were there for me when rumors swirled about me being closeted.I know that no amount of people I tell will ever be enough. It will always feel like I'm missing someone, and because of my slightly OC nature, it will always bug at me. But I can't do nothing either-- there needs to be some happy middle.Help?
