i’m constantly questioning my intentions and actions...

So, if I'm retelling a story or relaying information to someone, after I'm done speaking, my brain will send me thoughts like, "What if you lied? You might have told the story wrong! You're lying!" I've started second-guessing myself, even when I know I'm not lying or telling the story wrong😭 This has also bled into twisting my intentions behind certain actions... For example, the other day, I'd been babysitting my younger brothers. I'd gone to use the restroom and thought, "What if the door isn't locked or closed all the way?" Because this has happened once in the past. Turns out, it didn't lock correctly, and one of my little brothers almost walked in on me, but luckily, I shut the door in time, and we laughed it off. But then, I kept getting thoughts like, "You knew that would happen, and you didn't double-check! You wanted that to happen and for him to walk in!" :( I know this isn't true, but it's so annoying! Has anyone dealt with this? If you have, do you have any advice on how to deal with these thoughts?

I often feel like i did something wrong even tho i am positive i didn’t, my boyfriend and i have been together for like 6 months and i’ve been completely loyal to him the whole time but recently i’ve been feeling the need to confess that i cheated on him even tho i didn’t and there’s absolutely no proof that i did something even close, i don’t talk to other men and if i do my boyfriend has full access to my phone and it’s usually a friend or me asking a simple question but i still feel the need to confess even tho i’ve done nothing wrong🥲 someone please help it’s so confusing

I look back at various past events in my life where I said or did things that I feel really guilty, disgusted, and ashamed about. I replay them in my head for hours. I feel anxious about crossing paths with people that I've hurt or upset in the past or who perceive me badly, to the point that I will avoid going out in public as much as possible. I go out for work, errands, appointments, and occasionally to eat (even though those all give me a lot of anxiety), but I avoid community events where people might recognize me and I tend to isolate myself. The only people I see regularly are my boyfriend, my parents, and my coworkers. I live in a small community and I'm worried about people confronting me publicly and proving what a bad person I must be.
