Never get drunk and did what I did...

I had this friend I’ll call her (Kim) she fucked our friend (we’ll call her Skye) boyfriend. I found out and I was wondering why she stayed at his house for long periods of time when Skye was out of town. Well one night Kim told me to come over to Skye’s boyfriend house because they were drinking. I get over there and I get mad drunk! Me and Kim are kissing and Skye boyfriend joins in and we have a threesome in his bed. I woke up in the bed laying under him while Kim was on the other side I was dazed and confused and i pieced together what happened! I got up and threw up I felt so disgusting I couldn’t believe I did this to Skye I felt like shit! How could have I allowed myself to do the unthinkable! I jumped out of character! I started crying on the floor in the restroom. I felt so horrible and like a piece of shit. I got up and they were still in the bed sleep..I drove myself home and I told skye I needed to talk to her. I told her what happened...Kim denied everything and blamed me when she got me drunk and put the moves on me! Skye’s boyfriend even told her I started it! They denied it! Skye was mad but she forgave me. And Kim and skyes boyfriend still have sex till this day. But they keep it hidden. The end. I asked God to forgive me for my stupid sins! I always wondered if I was drugged or not because I wasn’t myself but I take my consequences as a woman.
