I'm no expert and I don't know you but sometimes when I feel like that it's because I can't get all the other thoughts out of my head. A thing that can help with that is put yourself in a space where you let your brain relax, like a spa day where you have to put your phone away (if you're addicted to your phone) or just leaving the house with no itinerary if you've always got things to occupy your head in the home. I sadly have no solution on how to get free time to do these things, if your day is completely filled, other than..pick the least priority thing and swap it out for some me time? Once you make room for the things you love, at least with me its easier to feel like I have "found the time".
