I'm working a temp job, due to finish in December. Desperately hoping a permanent contract will come out of it but no sign so far.
Meeting with boss's boss today. He wants me to give a presentation on my project to the entire department plus guest departmental leaders. Ok, you think, not so bad. What's all the fuss?
I tend to pass out when I have to give presentations.
I was the one they had to drag out of a cupboard feet first 
They forbade me from giving any more talks unless I was sat at the back of the room.
My mind goes blank if I get asked questions. Yes, I'm the one who got their date of birth wrong in a university interview
Boss at previous job would jump in and answer for me if I got too shaky.
If boss wasn't around a co-worker was my presentation colleague, either joint presentation, he dealt with questions. Or if it was lecture hall size, he did the entire presentation.
Literally my only chance of a job is to persuade these people I'm a confident professional. My boss's boss hopefully will apply to make a position for me, these people will be on the decision panel.
Tell me I'm not doomed!
