I’ve always struggled with sleep. A few things that helped me (in order of importance)

- go to bed and get up at the same time every day. Getting up is more important than going to bed.

- no phone in bed, and limit stimulating activities (intense video games, programming, planning the vacation etc) to 90 minutes before bed. I read during that time but TV, cleaning, music, whatever works.

- a bad nights sleep will happen, often a few nights in a row. Be ok with that (easier said than done, I did CBT for this). Instead of lying in bed restless get up and watch TV, or read.

- leave the house for 30 minutes every day.

- journal as often as possible. Ideally daily, but a few times a eeek. Don’t ever read it back but just write down your feelings and the things on your mind. Do good and bad.

- exercise every other day.

- no coffee after lunch, and never more than 3 in a morning.

It’s a marathon, not a sprint and overall I have way less bad nights than I did before, and I don’t beat myself up as much for the bad nights.
