Dirt under my nails????

Hey y’all, I am not a dirty person, but as someone with a mental disorder, I find it very hard to shower regularly. I promise I don’t stink, and I keep myself pretty clean, but one thing I can never seem to keep clean is my finger nails. They constantly have that little dark line of dirt under them. I live on a farm, and have recently been doing a lot of work with our cows (quarantine making me want to ride one of them 😂) so they are extra dirty. Any advice on either keeping my nails clean or general mental disorder hacks for someone with pretty severe ADD who struggles with daily tasks like showering? I also just got my hair dyed, so no more steaming hot showers for me, which is another barrier 🤷🏻‍♀️
