Me and my best friends had sex and I regret it

I’m a 20F and my best friends are 20F and 19F. When we were 17, we got drunk in one of my best friend’s room with our other friend. They both were with their boyfriends. We were so drunk and we played spin the bottle. We all started kissing each other. Their boyfriends were 23 and 21. I don’t remember everything but I know we all had sex… It’s going to be very graphic but I need to get it off my chest to move on. Me and my friend did ✂️ and we ate each other’s… you know. I don’t know why the f we did that. It’s so bad. I regret everything and I always remember that when i’m with my two friends. They broke up with their boyfriends a years later, and i’m so glad. I never thought about doing that. Never. I’m not even into girls. I didn’t even enjoy it. I think we just needed attention from those guys. And we wanted to please them. I don’t think I would ever move on from this. I think the only way to feel better is to stop being friends with those two girls. But we love each other so much, I don’t think I can do it. I just wish that nothing happened, and that we could be normal girl friends. Please someone tell me that it isn’t that bad…
