I actually suffer from social anxiety and OCD health-related anxiety as well. I commonly worry about things like pesticides, cleaning solvents, the sun's ultraviolet radiation light, radiation, cancer, toxic substances, etc. It feels like one is living inside of a prison, to be a slave to these mental disorders....
But don't worry, there are others just like you. That is what forums like this one are for. They are for reaching out and establishing a community, online, for interconnected support, with people supporting each other from all over the globe...
