For about a year and a half I struggled with guilt…

I am a 21 year old lesbian. I didn’t figure it out until I turned 20. I am also a Christian. For about a year and a half I struggled with guilt. I felt guilty because I had been told that homosexuality was a sin my entire life. That it was something to be ashamed of. But I was also struggling because I really didn’t understand why it was wrong. I also couldn’t tell my parents because they felt it was wrong and I wanted to figure out what how I felt about it before they started telling me how they felt about it. A few weeks ago I realized I don’t think that it is wrong anymore. I felt so much lighter and I had peace for the first time since I found out I that I was gay. I still haven’t told my parents…I am trying to figure out what to say, because now I not only need to tell them that I’m gay, but also that I don’t think it’s wrong anymore.
