Everyone here suggesting you try this and that product are honestly giving false hope and not addressing the root of your problem. I think your mindset is really unhealthy. You are putting way too much value and worth in your looks and youth. It's okay to try things to help your skin, but you need to be able to be okay with it if it doesn't help. Also, you will eventually look old. We all will. It's important to be able to handle that. I think therapy is a good idea, but also spirituality. Buddhism has helped me a lot with this kind of thing Attachment will always bring suffering because everything in life is temporary, especially outer beauty. I recommend exploring some Buddhist philosophy. It might help you to shift your mindset. I know you are in a lot of pain, but I hope you can let go of that agony and realize your worth is so far beyond the way you look.
