Instagram exposition

Hey everyone, umm god this is my first time doing this so let's give it a try! today two of my best friends managed to find out a secret social media account of mines, in which I post very NSFW stuff, and I also send nudes to people there as well...this is truly a nightmare for me, it really is because now I'm scared, my heart is beating so so fast and I cant sleep at all! Worried that more could find out or already have, or if my relationship with my two friends will be over! To keep the story short, I somehow accidentally put my full name into the bio, no knowing this I logged out and continued on with my day. Until both of my friends messaged me asking if that was me, screenshooting the account bio and there it was, my full name right ontop of the fake name I use. I didn't know what to do so I pani6and quickly said it was not me, my other friend(let's call him Tim) seemed to believe my false story about the account and how there are a bunch of people with my name. But my other friend on the other hand(let's call him Sam) seems to have suspicion it is actually me, since right after he told me, I quickly removed the full name and told him that I didnt see my name on there when I supposedly checked for myself. Now I am here, scared for my life, for my relationships...the worst part out of all this is that i have a girlfriend, a very lovely girlfriend. Yes, please tell me that I'm a horrible person because I am, I deserve to have that title...
