Could this be depression?

There was a time in my life when I never thought I would have a difficult day because I couldn't sleep. I loved sleep so much that I was teased for falling asleep as soon as I touched the back of my head, and I was the type to fall asleep easily regardless of the place. However, as I entered middle age and went through menopause, I developed insomnia. Of course, with various changes in my personal life and worries increasing, I think psychological factors also played a big role. At first, I thought it was just temporary and that I wouldn't be able to sleep well, but I couldn't sleep well.

As a year and then two years pass, I feel increasingly depressed and become pessimistic about my situation. My anxiety about the future adds to my inability to sleep, creating a vicious cycle. Could this be depression? I hear that counseling might help improve things... but I don't think I want to share my story openly, so I feel it might not be very effective... The prolonged unstable state makes me think a lot.
