Kinda sad and need to rant 😢

I started a new job on the 9th this month and I want to cry most days. It's no one's fault but mine bc it's not like anyone is mean to me or anything like that. I am very open about when I make mistakes and own up to absolutely anything and everything and I don't point finger's. If anything I will take the blame and leave it at that but it's all definitely a front.. I actually cry when I get home even if it's something that took 5 seconds to fix. I kept two girls I work with for an extra almost hour after work so the Dr. could fix a mistake I made unknowingly... Idk why I bask on things like this and I constantly think about it, it's like torture.. I feel like the dumbest person alive when I make mistakes. In the process of us trying to figure out what happened the doctor was asking me questions and when I replied he said "well computers don't lie." Which to me sounds like he was technically calling me a liar.. In the end we figured out what happened and it was something small and an honest mistake and I explained exactly what happened perfectly and why it happened so we all definitely learned from it. But even though we moved past his little comment it's just been eating at me. Do people really think I can just easily tell a lie like that? Do I give off that impression? Like I'm crying rn bc I am an honest person. It's probably one of the only things I'm proud of about myself. I own up to everything tiny harmless things to bigger more important things, I will not lie to anyone... my husband says I'm over thinking it just like I have with everything else at this job but ugh I'm just flustered and embarrassed and feel stupid and all of those bad things..
