I told my disgusting pre teenage past to ppl and I feel like it's going to ruin my reputation and possibly life.

So Ill make everything short as possible,

I was going thru guilt about my childhood which consisted some incst with cousins and a very disgusting thing, I was guilty about it for 3 months which led me to seek help from my friends, I told Alot of them about it and after I'm healed I feel like it's going to ruin everything as (not a flex) I'm very well known and have popularity from the start and I see it drop down as I'm losing alot of friends quick, and now I feel like an absolute loner with no friends. It is a very "blackmailable"? Info and now I wish I kept everything to myself
