How do I stop over analyzing everything?

Hey everyone, I just wanted to share something I’ve been struggling with, especially around making decisions. It’s really hard for me to feel confident in the choices I make, even when I know what the right thing is. I constantly find myself needing validation from others—whether it’s about something small or something really important. For example, at my job, I might know exactly what I’m doing and have done it right a bunch of times, but I still feel the need to double-check with someone or ask if it’s okay. It’s like this fear kicks in, and I start imagining worst-case scenarios—like what if I mess up and someone gets hurt, and then I get blamed or even end up in jail or prison. I know that sounds extreme, but these thoughts just come automatically, and they feel so real in the moment. This has been going on for maybe a year or two now. Even outside of work, the same thing happens. Like recently, I’ve been trying to figure out a gym schedule—my girlfriend wants to go with me, and I’m trying to plan the times and make it all work. But instead of just choosing what works best for me, I overthink it. I go back and forth in my head, and I ask other people what they think, even though deep down I know this is something I should be deciding for myself. It’s my life, but I still need that reassurance from others, and I don’t really know why. It’s exhausting to always doubt myself and to feel like one wrong choice could lead to something terrible. I’m trying to work through it, but I just wanted to put it out there and see if anyone else deals with this or has advice. Thanks for reading.

Is it normal to analyze every thought & feeling you have? For example. If I had a feeling like I wanted to flirt or if I felt like I wasn’t sad when my partner left for the night ETC. I over analyze these and they lead me to thinking I’m a bad partner or it’s not the right relationship. This scares me so bad Is this basically ROCD in a nutshell? It feels so overwhelming when thinking about all the different feelings and thoughts I’ve had over time
