You need more morning light. Get a couple of full spectrum lamps.

I feel for you. I've always been a night owl, and getting up really early has always been very hard. When I was young, I found it very hard to get to my job by 7:30. Sometimes it seemed so hard and horrible to go out into the cold and dark. It seems kind of silly to me now, but it was very real then. But even now, getting up before sunrise seems like it would be very hard. Thankfully, I don't have to.

For many yeasr I had to leave for work before my kids woke and arrived home after they were asleep.
Gave that away, but it did creep back in.
Past decades I still rise before dawn but watch the sunrise over the ocean with my kids.
Much better, even if we have to leave soon after for work.

We have a dog. If you have a dog, you get up before dawn, but there's a good reason for it and you get your face licked.
