Compulsion or apology worthy??

Months ago I made a mistake at work and I havent brought it up. Im a grad student and part of my work is in the lab. I took some things out of the lab and into a different lab where there's more potential for cross contamination and I'm worried I may have contaminated them and someones lab work will be messed up but because I didn't say anything they'll never know. I feel like I need to announce what happened but it's been months, and I dont actually know if I did contaminate anything and Im embarrassed so I'd rather not. But it keeps popping up and haunting me. I know my OCD is at play right now, I'm not sure if this is a real fear or not...but I also think what I did was wrong, like there's a pretty common protocol to not take that stuff out of the lab, I just didn't think about it at the time. I could tell my advisor on Wednesday and see what she thinks I guess, but in the meantime I'm feeling consumed with guilt and it's hard to work. I know this is possibly an urge to confess so maybe it's good for me to wait? Any thoughts??

One thing that I’ve noticed about my OCD is that it makes me feel very regretful and embarrassed at the end of every day. I reflect on every interaction and every conversation and any thought that I’ve had throughout the day. As a result, I feel more and more ashamed of the way that I act, even though it is probably normal for some of my age to act and see the things that I say. Earlier today I flirted with a guy and then as soon as it ended I had so much religious and moral guilt about it. Does anyone have any advice on how to not feel so ashamed after doing the typical activities that people in their 20s do? I feel like these thoughts are making me want to isolate from everyone else so that I’m not put in the position to do and say these things. I feel comfortable with myself when I don’t talk to anybody but I’m noticing that that can’t be normal . I don’t want to lose friendships and potential relationships out of fear that I’m going to say something wrong. I don’t know what to do.

For my job I had to get hired and apply to this company to get paid and I started the paperwork and thought I was doing it right but then I got busy and kind of forgot about it and they sent me so many emails that I would dismiss because I figured they were just reminding me to finish the rest but I didn’t read far enough where it said I had to get it done within 2-7 days so then my account got deactivated and I had to call their support line and the man was so mean to me and told me I was an unreliable worker even though I’ve been working this whole time and I’m always the first one to cover a shift when needed and even go to work when I’m sick and it just made me so upset. I know I was in the wrong but I have never seen someone be so rude to a person they do not even know. I’m an absolute mess. I was so mad that this led me to say something I didn’t mean which were along the lines of “I want to kill that guy I’m so mad” which obviously I didn’t mean at all, I was just really upset but now I think my ocd is latching to that statement bc I feel so guilty and I feel so bad for even saying it out loud. Is this normal? Was this ocd? I’m just so confused and depressed at this point. I feel like everything in my life right now is just spiraling emotion wise.
