It's a daily process, in my view. You have a visual gift apparently in your photography work.
Why don't you persist daily at evening in trying to picture a broom just sweeping
from your mind all the negativity that has built during the day? Gradually, you will make that a practice and will be able to rid yourself of each day's negativity. Negativity is a loading for depression.

I do that often and have an active prayer life.

In addition, I picture myself in a shower letting all the water just drain away all the
negative images, things that have been said that are painful, noise, and especially
any anger. Grief is a good one to let go, too. Your child within will thank you for
that as she grows and feels "covered" by the love of the inner adult. I almost said
"parent" but that could be a futile effort if the parents were not nurturing. So I
use the word "adult" instead, because that suggests that we have become our
own person. (I think that's probably why you feel independent, and it's a wonderful
feeling, isn't it?)

Remember, there's a lifetime of goodness awaiting everyone who makes the effort
to improve the inner child's life and learns to respect and care for the inner child of
others.

Suddenly you find yourself not impressed so much with how people are dressed or
look or feel. You just sense a child within them who is either happy, free, or sad
and dismayed. Compassion will pour from you like a living spring.

Take good care of yourself. I think you're doing wonderfully well.
