I understand it's hard to get peace when stuck in home. Give time to Prayer and Bible as much as you can in other times try developing healthy hobbies like learning piano(or any instrument would do), rubiks cubing, hand writting imrpovement, reading books, learning a new language to name a few. Don't think I'm a nerd because I'm not, definitely NOT. So these activities can be fun and good for your brain at the same will be useful in some point of your life. If you still think it's impossible. There's one solution that always works for me. Just think it's possible and start to doing something.
