Hello, I too have recently been diagnosed with an anxiety disorder and been put on antidepressants - not Diazepam though. I promise you this is just a state of mind. I don't have the answers as to how to make it better, but hopefully one day soon it will be. I experience the same things as you and also worry about things which I know are totally irrational and aren't really likely to happen. You are not 'cracking up' and you aren't the only one who feels this way, so let that be the least of your worries.
