> You’ll probably take this the wrong way but I have no other way to say it. If are not in grief over your past, you truly had a poor past, or you have not yet realized the significance of it.

Not GP, but this is absolutely wrong.

I had a good childhood with loving parents, I had many friends growing up, and I enjoyed my free time.

I also enjoy that it came to an end. All good things nust end, else they have no value.

This is mostly because I achieved nice things in life. In many ways the present is the best time of my life. I embrace change. I like my adulthood, and as I grow older I will enjoy my old age while my health allows to.

Dwelling in the past is unhealthy.

Yeah honestly. I've made peace with the past being past. Life isn't all sunshine and daisies obviously, but its also not an inevitable depression. Things changing is a part of life and every new stage has different experiences available to it. That's really neat imo. Learning to make peace with that inevitability is not easy, but its a part of having a healthy outlook.
