Hello ! Have complete sympathy and experience huge self doubt - worst thing is trying to hang onto a career when blubbing in the office over a tiny error,,, agree with taking steps to push your personal boundaries, because the more you do the better.. also folks really aren' t that aware of you , so its ok to go for it, fail, get up and go for it again... CBT is great for this sort of thing but aware hormones do their best to drag us into a pit of uselessness. Work should be aware of diversity and all that so might be a forum there to discuss it. Also focusing on the task and its purpose I find helps me to stop thinking about what people must think of me. Sometimes trying to be like a swan helps.. making out you are ok , smile, look them in the eye, and somehow it can work to convince yourself it is ok...
