It takes courage to admit that you are struggling, Tree Nerd.
I had a bout of post-partum depression after son 2 was born (4 sons in all).
It was painful in so many ways, but I learned so much from the experience.
#1. I learned compassion toward other people instead of judgement.
#2. I am not invincible nor above struggling.
#3. One cannot always just try harder or think positively and fix everything.
#4. It is OK to let other people help you, humbling, but OK.
I would hope to never go through that again, but I am glad for the new perspectives it gave me.
You are on my prayer list, Tree Nerd.
