The biggest, fastest and easiest change that improved my depression was getting a light alarm: https://www.usa.philips.com/c-p/HF3531_60/wake-up-light https://www.usa.philips.com/c-p/HF3531_60/wake-up-light The usability of this model is terrible, but it changed my life, allowing me to get up consistently before 7AM without being groggy. Surprisingly it was the "sunset" feature that fades natural yellow sunlight light into a deep red that really helped by allowing me to fall asleep consistently when I wanted to. I can't guarantee it will work for everyone, but it made a large difference in my life.
