If you can't sit in a room and do nothing for 30 minutes.
Or read a novel for 2 hours without stopping.
You're brain is broken.
It's f*cking up almost every aspect of your life. Reversing this should be priority #1.
the best thing you can do for yourself is actively increase your surface area for luck to hit you. go outside, try new cafes, museums, events, take a new route home, speak to people, ask questions, side quest. the more you do, the more serendipity and synchronicity will find you.
If you're going to have a difficult or emotionally triggering day, eat protein and fat when you wake up. The stabilization of your glucose levels will help you regulate your emotions and think more clearly.
