This dovetails very closely with the previous post. Sacrament is an important part of applying the atonement daily in my life.
Before I spiraled, I had a pretty good understanding of the atonement. I had benefitted from it as I repented of sins. I had cognitive understanding it could be used for other things, but I had not experienced it strongly relating to weakness.
Because of what I was in the middle of, I could not do certain things, I could not motivate myself to do certain things. I was weak. And that weakness was not something I had experienced so poignantly before.
By going through that period, I had to pray for strength provided through the atonement every day.
Every day I struggled to gain, ask for, and receive the strength to push forward. Every day I had to humble myself and ask Father to give me strength from the atonement. Every day I was forced to recognize my weakness and work to accept it and overcome it with help.
The atonement is for sin. It is for pain. It is for weakness, generally and specifically. It is for broken hearts. It is for depression. It is for physical and mental shortcomings. It is for illness. It is for healing in every possible meaning of the word.
I understand it a little better now because I have been through more trials. Healing is real. It comes from atonement.
