A few months ago I began suffering from this anxiety-related rash. The symptoms are as follows: red blotchy skin, and mosquito bite-like bumps that cover my chest arms and neck. The discomfort level can range from mild to extremely agonizing. The worst part of all is that it is easily triggered by mild stress, anxiety, embarrassment and even heat! If there is a hell, THIS is what it'd be like. So I went to go see a doc, which gave me some lexapro. After taking it for the first time, I felt like I was going insane. Needless to say, I stopped taking that. After several more unsuccessful attempts with the doctor, it had gotten to the point where I began self-medicating illicitly acquired drugs to combat this problematic condition. What alleviates the suffering for me, as i found, is potent painkillers. Since I have developed a tolerance to said drugs, i no longer take them to feel good, only to not feel horrible. I hope that I don't have to deal with this for the rest of my life as some poor souls. For those of you who share the same condition, but do not wish to deal with drugs, I have discovered a promising alternative. There is a plant root named Kava, it is 100% legal and can usually be found in most supermarkets. The root has incredible calming effects akin to those of alcohol and pot. It makes even the most nervous of people sociable and outgoing thereby preventing the anxiety rash. I highly recommend it. (If you do buy some, I suggest getting the root powder. Don't get the extracts or any other stuff like that).
I envy those without this horrible condition. Good luck to those like me.
