Everything is from Him
I am, B"H, very successful in everything in life, besides for my addiction. I feel that Hashem gave me this struggle to remind me that everything is from Him! If not, I would forget about Hashem completely and only focus on my success - and how I am on top of the world. Hashem created this shame, so we could want to come close to Him and realize that He is the one running the show completely!
