I don’t know what to do.

So i and my 7 friends went to hut. When we all unpacked our lugages we decidet to drink. It was my first time drinking strong alcohol. I and one of my friend(X) got really drunk. Others were ok but they were anoyed because we were too loud. Then my friend X and I were sent to sleep in another room. We laughed a lot and didn't want to sleep. Then she asked if i want to kiss . I thought it was funny (because i was drunk) and i agreet. So we kissed a lot and i even gave her a hickey. In the middle of kissing i told her that i think iam Bi, she just said something like “Ok” and we continued to kiss. Then she said she wasn’t felling good and that she wanted to puke. After i went to toilet and others were helping that friend X because she wasnt felling good(she puked) i went to bed. All my friends told me to go to bed so I pretended to sleep but in reality i started thinking about what I did (I was still drunk). After my friends helped friend X,she fell asleep.In the morning i realized what i did.When we were all together, one friend asked friend X where did she get a hickey( i started to panic) she didn’t tell who did it. I know friend X remembers everything but we were avoiding each other.
Now i am home and writing this. She is a really Good friend and i dont want to ruin our friendship. What do i do ?
