Help I feel like a horrible person

Okay so, two years ago, when i was 13-14. I met this group of people on minecraft, we shared our discord and we made a group chat. I was insecure of my face and body because of another group of guys made fun of me on discord once before.

I became best friends with a girl in the chat, and I liked a guy in there too. So I sent really pretty girl's instagram pictures when we did face reveals, saying it was me. He said the girl was really pretty.. (The only fake thing about me was the photos and my name)
We talked, and finally got together... He talked about how much he wanted to see me, and he wanted to fly over and meet me. This absolutely scared me, and I wanted to tell them all the truth but instead i ditched.
I eventually came back, months later because i missed them.
I told them the reason I left was because my parents split and i was going through some stuff.... which was not true... He said that he was going through some things, and he hated me because I left. For my best friend, she was just happy i was back... But I was scared they would hate me if i told them the truth...

Now. Currently. I am dealing with the same guilt. They want to meet in 2 years time. What do I do. I love them all so much. My best friend, i can tell sent pictures of another girl and pretended it was her too, but she only did it twice, and is now showing her real face. But I never exposed her because I knew how she felt and I knew how she would have felt if i did.

Do I not send pictures for a while of the girl im pretending to be, and send one in a few years time when they forget the face. Or do I come clean...?
I'm scared I will lose them, yet I feel like I would deserve it..
I know what I did was extremely terrible and awful, so try to refrain from lecturing me. I made a mistake, now I just want them to know the real me...
