I need advice

this weekend, i went out with some friends who were staying with me from out of town and i drank too much. because of my job and mental health i very proactively limit how much i drink but i got caught up in the fun of the moment and drank past my limit. this morning, i woke up to a message from my boss about a tragedy that happened in my community this past weekend. my mind is rapidly trying to draw connections between me drinking too much and this tragedy. my ocd is trying to convince me that i caused it while i was drinking and that i just don't remember it. anyone else experience things like this? i'm trying not to seek reassurance but it's getting difficult!

For context, I was previously diagnosed with GAD and OCD. Months ago, after a night of drinking with coworkers I experienced slight hangxiety, but I remembered most of the night. At work when I asked a coworker if I did anything weird he made a joke that really wasn’t funny. This joke caused me to doubt my memory. I think I had thought I was more sober than everyone else when in reality I was not. I remember checking on a coworker who was slumped over in the drivers seat of his car and in no state to drive and asking “you good?” The next thing I remember is that I was in the drivers seat of his car reversing out and I think I assumed that he and our other coworker were also in the car. Our other coworker stopped me and told me to pull back into the parking stall and come back inside. I remember the events both leading up to and after that all the way until I got home. However the small gap in my memory had been causing me a lot of distress, so I asked that coworker who I went to check on who was the only person that was present during the gap in my memory if I touched anyone or let anyone touch me, to which he said no definitely not. He also said that he wasn’t in the car when I was reversing out and that he vividly remembers that I was the only person in the car. When I explained to him that the joke that our other coworker said made me worry that I might’ve done something that constitutes cheating on my bf he said no that guy is just weird and says effed up stuff. I feel a lot better, because he has no reason to lie and he doesn’t seem like that type of person. However I still feel unsettled, so I plan to call my doctor’s office when they open in the next hour. I’m wondering if anyone has experienced anything similar/has any advice.

I made a really stupid mistake over two years ago. I brushed it off and have just assumed everything was fine since. I even forgot about it. Recently, I saw a reel on my phone that triggered anxiety and ruminating about said mistake. Everyday when I wake up and fall asleep, it’s all I think about. I begun opening up to loved ones about the story and they all reassured me that everything’s fine, and that it’s really “not a big deal”. I’m still very much on edge, paranoid, and aware that it could come back to bite me in the ass. It’s consumed my mind so much to the point where I don’t enjoy the things I used to, it’s difficult keeping up with daily tasks, it has stripped me of my motivation and my relationships with other people due to isolation. I’m physically sick from worrying about the future, coming up with every worst possible case scenario and mentally living in that persona instead of what’s happening right now in front of me in the present.
