Hey YoungOne,
I've been feeling a lot of what you're feeling, and it is getting better. Day by day, it's getting better. It surpised even me...that horrible feeling has eased a bit. Little by little, it'll get better for you too.
No one deserves this, but things just happen. You should not think that you're a disappointment. Ever. When I found out, I was feeling so lost and so afraid, it was overwhelming. But I started to think of all that I have in my life - how fortunate I am to live where I live, to have my friends, my family, my pets, my job, etc. And I have to remind myself to put things in perspective. I can guarantee that there are a lot of people who would trade places with you in an instant if they could. There are some ghastly diseases out there and we don't have one of those diseases. Just as brighteyes says, we have a very common, very treatable skin irritation. Every so often it may become an inconvenience, but we can treat it and move on. And you have your youth! That may sound so cliche, but it's true. Enjoy it. Keep reading this forum because it is helping me bounce back and they will help you.
If I were in front of you I'd reach over and give you a big big hug.
