I am so sorry for what you are experiencing. Mine was a very bad case that basically kept me socially isolated until I was 20. No friends, no dating. My Mom also made the mistake of telling a family member, when she thought I was not within earshot:: “He just has a face only a mother could love.” Crushing. But hearing the Gospel for the first time after that was a spiritual and “whole person” lifeline.
Still, I felt so isolated, that I enlisted in the military just so I could be around people—even if it was the trials and travails of basic training. The experience got me out of negatively spiraling thought patterns.
As for physical healing, I had to self diagnose myself, as nothing worked except very heavy dosage of tetracycline. Bottom line, my acne drastically cleared up after eliminating all refined sugar, eggs, honey, white flour, shellfish, fruits high in fructose, and nuts. I am not saying you should follow the same course, but it could help to observe how your skin “reacts” with/without certain foods.
I am 67 and am still working through the emotional scarring. It jolted me when my wife told me a few years ago, “Why don’t you ever look at yourself in the mirror?” Habit, but it got me thinking. Trusting my Creator means that He values me as a significant part of the Body of Christ. It is so healing to know you belong.
Concentrate on the latter with all your might, please. I pray for you!
