I'm so so so nervous over something that may never happen

Hi guys this is a throwaway

So I just kinda need to vent but I'd also really appreciate some advice

I'm currently a 21 year old female and when I was 17 going on 18 I used to masturbate on Omegle. I regret it immensely, looking back it was during the worst period of my life. I had gotten depression my final year of school and used it as a was of coping with myself if that makes sense? I was really lonely and just in a dark place and was on the verge of suicide, I hate thinking about that time.

Basically, it's been a couple years since that point, right? But for some reason, I can't help but ruminate on the possibility of myself appearing on a porn site or something. I did it a handful of times, so statistically someone might have recorded me. I also did slip my face in at some points during these chats, but usually it would be at a point where I would also see the guys face so it makes me think they probably didn't record.

I'm just throwing my thoughts down and rambling at this point but basically I also deal with anxiety on top of depression and have been obsessively thinking about this for a good 3 months. I think from this post it's clear how freaked out about this I am, even though if anything was posted and would be tracked down to me it probably would have by now. I just really really need advice on how I can stop thinking about this? When I initially stopped doing it I was able to move on easily but for some reason now I'm all paranoid. If it helps at all I don't have any social media in fear of being tracked down.

Please please if at least someone can tell me what I can do to stop thinking about this and move on with my life that would be fantastic. Thank you.
